02a27b50 23// This class stores the sample rate (that is, how many times the
24// ATLRO's sample each VA1 channel). In principle these can be
25// controlled per half ring, but in real life it's most likely that
26// this value will be the same for all detectors. This value must be
27// retrived from DCS or the like.
8f6ee336 28//
bd8f72a4 29// IMPORTANT: The member function WriteToFile writes out the entries
30// in the format
31//
32// det,ring,id,rate
33//
34// Here, id is a number from 0 to 1, which represents the division in
35// half-rings. The mapping is as follows:
36//
37// Inner rings: Outer Rings
38// id Sectors Board id Sectors Board
39// ----+---------+------- ----+---------+-------
40// 0 | 0 - 9 | 0x10 0 | 0 - 19 | 0x11
41// 1 | 10 - 19 | 0x0 1 | 20 - 39 | 0x1
42//
43// The same mapping is used in the ReadFromFile member function
