HCal Test-Calibration Sets

Currently, the following database folders providing calibration sets for testing are available:

/cd_calice/Hcal/Calib_Test/gain_constants 

/cd_calice/Hcal/Calib_Test/gain_slopes 

/cd_calice/Hcal/Calib_Test/mip_constants 

/cd_calice/Hcal/Calib_Test/mip_slopes 

Every entry gets tagged to allow permanent reference. Users are encouraged to use tags rather than the HEAD, i.e. make sure they know which assumptions are valid on the constants they use.
