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.

Description

ahc_gain_constants_t001

all

Gain values extracted from linear fit to CERN 2007 measurements and extrapolated to 27.0 degrees centigrade (corresponds to the average temperature of all gain runs at CERN).

all

Absolute slopes extracted from linear fit to CERN 2007 measurements.

ahc_gain_slopes_t002

all

Absolute slopes extracted from linear fit to FNAL 2008-4 measurements (after 3rd HV adjustment).

ahc_gain_slopes_t003
