For runs using the CAL-SLT (physics runs) SLT constants are read from a file in directory /calcon/cslt, named sltconstvnnnn.fz, in which nnnn is a 4-character version number. The file is in ZEBRA-format.
The version number used is the number on the 27th line of the DAQ configuration file (the line with the comment: CAL-SLT/polynomial constants version).
