+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 RICH 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 RICH has no any private header, just uses the common one.
+
+Single RICH 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
+
+RICH 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.
+
+RICH 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)
