MythenFileReader

File reader to read acquisition files stored as hdf5. The filereader inherits from a wrapper class based on the C++ API of the HDF5 C Library. The provided dataset need to have fields data storing the photon counts, DetectorAngle storing the detector position in degrees and CounterMask storing which counters are active. The field CounterMask stores an integer representation of a 3-digit bit string, where each bit is set to 1 if the counter is active.

Example

CounterMask: 4 // binary representation 1 0 0
only channel 0 is active
CounterMask: 3 // binary representation 0 1 1
channel 1 and 2 are active
