19 @brief Per digitizer card pulser calibration
21 //____________________________________________________________________
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.
29 // IMPORTANT: The member function WriteToFile writes out the entries
34 // Here, id is a number from 0 to 1, which represents the division in
35 // half-rings. The mapping is as follows:
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
43 // The same mapping is used in the ReadFromFile member function
