Detailed Description

Allow saving and retrieving of calibration constants to/from txt file. This was originally provided for backward compatibility with the ORCA MuBarDigiParameters file. Can be used to save an arbitrary number of constants with the needed granularity and to retrieve them back using the wireId. Current field allocation: fields for each key are allocated to: –First block: legacy descriptors– [0] ttrig [1] sigma_ttrig (obsolete) [2] kfactor (obsolete) [3] vdrift [4] sigma_vdrift (obsolete, was formerly hacked to include reoslution) [5] t0 [6] t0rms [7] noisy or dead flag [8-9] left for future usage –Second block (optional): free fields [10] Encoded information of free fields: (1000*version)+(100*type)+(number of fields); type is: ttrig=0, vdrift=1, uncertainties=3 [11-end] free fields
