+// This class stores the sample rate (that is, how many times the
+// ATLRO's sample each VA1 channel).  In principle these can be
+// controlled per half ring, but in real life it's most likely that
+// this value will be the same for all detectors.  This value must be
+// retrived from DCS or the like. 
 //
+// IMPORTANT:  The member function WriteToFile writes out the entries
+// in the format 
+//
+//     det,ring,id,rate
+//
+// Here, id is a number from 0 to 1, which represents the division in
+// half-rings.  The mapping is as follows: 
+//
+//  Inner rings:              Outer Rings
+//    id   Sectors   Board     id   Sectors   Board 
+//   ----+---------+-------   ----+---------+-------
+//     0 |  0 -  9 |  0x10     0  |  0 - 19 |  0x11
+//     1 | 10 - 19 |  0x0      1  | 20 - 39 |  0x1
+//
+// The same mapping is used in the ReadFromFile member function
