27// MCT1ReadPreProc
28//
29// Reads a output file of the CT1 preproc.
30//
31// Implements usage of a selector (see MRead) Use such a filter to skip
32// events before reading! But never use a filter which needs read data
33// as input...
34//
35// Input Containers:
36// -/-
37//
38// Output Containers:
39// MCerPhotEvt the data container for all data.
40// MPedestalCam ct1 pedestals
41// MMcEvt monte carlo data container for MC files
42// MMcTrig mc data container for trigger information
43// MSrcPosCam source position in the camera
44// MBlindPixels Array holding blind pixels
