19 | // Class AliSignal | |
20 | // Generic handling of (extrapolated) detector signals. | |
21 | // | |
22 | // The user can decide to store either calibrated or uncalibrated signals. | |
23 | // Via the specification of a gain and offset or/and an explicit | |
24 | // (de)calibration function both calibrated and uncalibrated signals | |
25 | // can always be obtained. For details see the documentation of the | |
26 | // memberfunction GetSignal() and the class AliAttrib. | |
27 | // The explicit specification of a (de)calibration function offers the | |
28 | // maximum flexibility and also allows automatic indication whether | |
29 | // calibrated or uncalibrated data has been stored. | |
30 | // The latter can be achieved by only specifying a calibration function | |
31 | // (and no de-calibration function) in case uncalibrated data is stored, | |
32 | // whereas in case of stored calibrated data the user should only | |
33 | // provide a de-calibration function (and no calibration function). | |
34 | // | |
35 | // Note : | |
36 | // ------ | |
37 | // Signal positions (r) and reference frames (f) are specified via | |
38 | // SetPosition(r,f) under the following conventions : | |
39 | // | |
40 | // f="car" ==> r is Cartesian (x,y,z) | |
41 | // f="sph" ==> r is Spherical (r,theta,phi) | |
42 | // f="cyl" ==> r is Cylindrical (rho,phi,z) | |
43 | // | |
44 | // The same holds for SetPositionErrors(). | |
45 | // | |
46 | // All angles are in radians. | |
47 | // | |
48 | // Example : | |
49 | // --------- | |
50 | // | |
51 | // AliSignal s; | |
52 | // s.SetName("Start counter"); | |
53 | // Float_t pos[3]={-1,25,7}; | |
