+/*
+Any given LDC collects data from a number of D-RORC cards connected to this same LDC by separate DDLs. This data is stored in corresponding number
+of DDL buffers.
+
+Each DDL buffer corresponds to a single D-RORC. The data this buffer contains are hardware generated by D-RORC. The buffer starts with common header
+which size and structure is standartized and mandatory for all detectors.
+The header contains among other words, so called Equipment ID word. This unique value for each D-RORC is calculated as detector ID << 8 + DDL index.
+For HMPID the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13.
+
+Common header might be followed by the private one although HMPID has no any private header, just uses the common one.
+
+Single HMPID D-RORC serves one half of a chamber i.e. 3 photocathodes even LDC for left part( PCs 0-2-4) and odd LDC for right part(1-3-5)
+as it's seen from electronics side.
+
+So the LDC -chamber-ddl map is:
+DDL index 0 -> ch 1 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601
+DDL index 2 -> ch 2 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603
+DDL index 4 -> ch 3 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605
+DDL index 6 -> ch 4 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607
+DDL index 8 -> ch 5 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609
+DDL index 10 -> ch 6 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b
+DDL index 12 -> ch 7 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d
+
+HMPID FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows.
+Each DILOGIC chip serves 48 channels for the 8x6 pads (reffered in the code as kDilX,kDilY). Channels counted from 0 to 47.
+
+The mapping inside DILOGIC chip has the following structure (see from electronics side):
+
+5 04 10 16 22 28 34 40 46
+4 02 08 14 20 26 32 38 44
+3 00 06 12 18 24 30 36 42
+2 01 07 13 19 25 31 37 43
+1 03 09 15 21 27 33 39 45
+0 05 11 17 23 29 35 41 47
+
+ 0 1 2 3 4 5 6 7 padx
+
+10 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure.
+DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10.
+24 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes.
+Rows are counted from 1 to 24 from top to bottom for right half of the chamber (PCs 1-3-5) as seen from electronics side, meaning even LDC number
+ and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number.
+
+HMPID raw word is 32 bits with the structure:
+ 00000 rrrrr dddd aaaaaa qqqqqqqqqqqq
+ 5 bits zero 5 bits row number (1..24) 4 bits DILOGIC chip number (1..10) 6 bits DILOGIC address (0..47) 12 bits QDC value (0..4095)

+Any given LDC collects data from a number of D-RORC cards connected to this same LDC by separate DDLs. This data is stored in corresponding number
+of DDL buffers.
+
+Each DDL buffer corresponds to a single D-RORC. The data this buffer contains are hardware generated by D-RORC. The buffer starts with common header
+which size and structure is standartized and mandatory for all detectors.
+The header contains among other words, so called Equipment ID word. This unique value for each D-RORC is calculated as detector ID << 8 + DDL index.
+For HMPID the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13.
+
+Common header might be followed by the private one although HMPID has no any private header, just uses the common one.
+
+Single HMPID D-RORC serves one half of a chamber i.e. 3 photocathodes even LDC for left part( PCs 0-2-4) and odd LDC for right part(1-3-5)
+as it's seen from electronics side.
+
+So the LDC -chamber-ddl map is:
+DDL index 0 -> ch 1 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601
+DDL index 2 -> ch 2 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603
+DDL index 4 -> ch 3 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605
+DDL index 6 -> ch 4 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607
+DDL index 8 -> ch 5 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609
+DDL index 10 -> ch 6 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b
+DDL index 12 -> ch 7 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d
+
+HMPID FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows.
+Each DILOGIC chip serves 48 channels for the 8x6 pads (reffered in the code as kDilX,kDilY). Channels counted from 0 to 47.
+
+The mapping inside DILOGIC chip has the following structure (see from electronics side):
+
+5 04 10 16 22 28 34 40 46
+4 02 08 14 20 26 32 38 44
+3 00 06 12 18 24 30 36 42
+2 01 07 13 19 25 31 37 43
+1 03 09 15 21 27 33 39 45
+0 05 11 17 23 29 35 41 47
+
+ 0 1 2 3 4 5 6 7 padx
+
+10 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure.
+DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10.
+24 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes.
+Rows are counted from 1 to 24 from top to bottom for right half of the chamber (PCs 1-3-5) as seen from electronics side, meaning even LDC number
+ and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number.
+
+HMPID raw word is 32 bits with the structure:
+ 00000 rrrrr dddd aaaaaa qqqqqqqqqqqq
+ 5 bits zero 5 bits row number (1..24) 4 bits DILOGIC chip number (1..10) 6 bits DILOGIC address (0..47) 12 bits QDC value (0..4095)

+How to deal with the stack of particles?
+ - first of all, the stack includes primary as well as secondary particles
+ - pointer to the stack is taken:
+ AliRun::Stack() (global gAlice of type AliRun - deprecated way to do)
+ AliRunLoader::Stack() but before one needs to load event header by AliRunLoader::LoadHeader() otherwise both methods return 0.
+ Moreover loading header gives the information about number of particles only.

+ Responsible method is AliHMPID::Hits2SDigits
+ One hit may affect one or more pads.
+ Hit position is taken on the anode wires plane as the most of avalanche is developed there.
+ This position is not directly available, track intersections with entrance and exit of amplification gap are only stored.
+ So the position in the middle of the gap is calculated as average out of pHit->In() and pHit->Out() positions.
+ Then, total charge collected for this hit is calculated by AliHMPIDParam::Hit2Qdc.
+ Area of disintegration is a list of pads affected by current hit. This is a parameter of Mathienson
+sdigits->digits:

+HMPID calibration and alignment.
+
+Abstract
+HMPID calibration and alignment strategy is described with emphasis put on those aspects of the procedure which are relevant for reconstruction and thus the final detector
+figure of merit. In particular, the refractive index calibration technique based on mass plot shifts analysis and chamber alignment with respect to core detectors
+are explained in details. External sources of calibration and alignment data are also mentioned as well as the way HMPID intends to handle those data, including initial CDB
+creator.
+
+Calibration.
+Looking on HMPID chamber structure, full description of which is available elsewhere (ref RichTDR), easy to compile the table of all possible parameters affecting reconstruction.
+The first one of major importance is a freon refractive index. Although the full optical path visible by photons includes freon vessel, proximity and amplification gaps filled
+with methane and quartz window separating above mentioned volumes, only freon refractive index is subject for calibration. Refractive index of SiO2 window is not practically
+affected by any external parameters, while influence of methane temperature to it's refractive index is negligible. So it's enough to measure there optical curves just once.
+In the rest, the only changeable parameter is refractive index of freon. Temperature influence on freon refractive index was measured experimentally. The parametrization
+found to be:
+ n=n0-0.0005(T-20) where T is freon temperature in degrees Celsius
+ n0=Sqrt(1+ 0.554*lamda^2/(lamda^2-5796)) where lamda is photon wavelength in nm taken at 20 degrees Celsius
+Preliminary, the parametrization itself is considered to be permanent one. The only parameter to store and retrieve is freon temperature. Since this value is available from
+DCS DB and expected to be served by a SHUTTLE program which is not yet ready, the following temporarily solution has been adopted.
+In local CDB storage (default directory is $ALICE_ROOT) two versions of freon refractive index are written by external macro RichCdb.C :
+Run0_0_v0_s0.root contains DiMauro's parametrization and the temperature is set to 20 degrees. To be used as default for simulation and reconstruction.
+Run0_0_v0_s1.root contains DiMauro's parametrization and the temperature is set to 50 degrees. To be used in special uncalibrated reconstruction to test calibration procedure.
+Both of them are valid in run range from run number 0 to run number 0, thus in no way affecting any normal operations.
+
+Refractive index of freon (C6F14) is taken in AliHMPIDRecon for 3 different photon energies by means of 2 methods: Set
+
+
+
+Alignment.
+Information about detector position and orientation is needed during reconstruction phase. This information affects track-cluster matching procedure, the relevant peace of
+code comes to AliHMPIDTracker::PropogateBack(). Matching procedure consists in prolongation of the track reconstructed in core detectors up to each HMPID chamber plane in
+a sequence. The plane used is the entrance to HMPID radiators. If the intersection exists and inside the sensitive area, the point of intersection is to be transformed to HMPID
+local reference system. Note, that in this check, the dead zones in-between radiators are not taken into account. This operation requiring MARS to LORS transformations is done
+in AliHMPIDHelix::RichIntersection(). Plane to be intersected is defined by a point belonging to that plane served by AliHMPIDParam::Center(ChamberNumber) and a vector normal
+to the plane served by AliHMPIDParam::Norm(ChamberNumber). Transformations itself are done in AliHMPIDParam::Mars2Lors() and AliHMPIDParam::Lors2Mars(). Internaly in AliHMPIDParam,
+each chamber is represented by TGeoHMatrix. It's worth to stress again that geometry related operations are needed to be done for 3 different planes per chamber, namely entrance
+to radiator, anode wires plane and photocathode plane. So AliHMPIDParam sustains 7*3=21 planes. Also important to say, that direct usage of TGeoHMatrix::MasterToLocal()
+and vice versa is not possible due to special nature of HMPID LORS. According to the decision made about 3 years ago, HMPID local reference system is centered in low left
+hand corner of the chamber if one looks from outside to direction pointing to intersection point.
+So the most obvious candidate for alignable objects to be stored are these 21 TGeoHMatrix objects.
+The approach suggested in AliAlignObj is not quite feasible mainly due to the fact it relays on incrementing procedure using import from geometry.root. HMPID geometry is defined
+in a way that there is no volumes exactly corresponding to the HMPID planes.

+Geometry of HMPID chambers.
+After the decision to rotate the whole HMPID setup from 12 o'clock position to 2 o'clock position we have the following situation:
+
+Theta = 109.5 degrees for chambers 1,3
+Theta = 90.0 degrees for chambers 2,4,6
+Theta = 70.5 degrees for chambers 5,7
+
+Phi = 50.0 degrees for chambers 6,7
+Phi = 30.0 degrees for chambers 3,4,5
+Phi = 10.0 degrees for chambers 1,2
