/*
-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.
+Preface: all geometrical information (like left-right sides) is reported as seen from electronic side.
-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 DDL file 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.
+Single HMPID D-RORC (with 2 channels) serves a single chamber so that channel 0 serves left half (PCs 0-2-4)
+ 1 serves right half(PCs 1-3-5)
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
+DDL index 0 -> ch 0 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601
+DDL index 2 -> ch 1 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603
+DDL index 4 -> ch 2 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605
+DDL index 6 -> ch 3 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607
+DDL index 8 -> ch 4 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609
+DDL index 10 -> ch 5 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b

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.
+Each DILOGIC chip serves 48 channels for the 8x6 pads Channels counted from 0 to 47.
