will mainly affect the subroutine calculateHTRFrameTimes
more precise calculation of TIMEDEL should be performed
by reading CCF ModeParam
the warnings called from the HTR processing should really be

selection criteria for bad frames may be obtained from the CAL
and user supplied selection expression.
The conversion of SER into GRADE and SHAPE could be performed by
a CAL function.
