Folks,

I have updated the SC_CALIBRATIONS map in the $CLAS_PARMS area with the
following information (format: item -- earliest run number in map):
(1) effective speed of light for each counter -- 7500;
(2) Time walk corrections for sectors 3,4,5 panels 2 and 3 -- 7500;
(3) A correction factor for the December TDC calibration values -- 7500;
(4) Time-walk reference adc of 8100 ch for December run -- 7500;
(5) Time-walk reference adc of 600 ch for February run -- 8200;
(6) New TDC calibration with more correct pulser interval -- 8200
(7) Time-walk corrections for forward carriage and sectors 3,4,5 panels 2
and 3 based on new TDC calibration -- 8200

I have also modified the SC code to use the two new map entries (ADC ref,
TDC calibration correction).

Simon.
