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. | |
28 | // | |
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 | |
