28// This is a task which
29// - calculates the position of the source in the camera
30// from the position of a known star in the camera
31// - and puts the source position into the container MSrcPosCam
32//
33// Input :
34// ASCII file containing for each run
35// - the run number
36// - the direction (theta, phi) the telescope is pointing to in [deg]
37// - the position (xStar, yStar) of a known star in the camera in [mm]
38// - the error (dxStar, dyStar) of this position in [mm]
39//
40// Output Containers :
41// MSrcPosCam
