The bad channels, -1111, are really impossible to fit! channel 10, 19
and 26 was refitted by hand, since there were very ragged broad peaks in
these slats. The Br[Tof,BB]TdcGainCalModule::FindMax() function's
selection of peaks has a hardcoded constant. This made the fitting go
wrong sometimes, especially when it found more than the expected number
of peaks (see the bad channels in the attachemnt)! They were really
horrible! I wrote a short program to do the refitting. If there are more
than the expected number of peaks, the algorithm takes all the
selections of the expected number of peaks from the N found peaks. It
then fits all these selections and compares the chi2. The one with the
best chi2 is keep.
slat 17, 27, 42 and 43 are impossible to calibrate...
The right TOFW tdc file is now attatched (supplied the one without
handfit corrections the first time)
