Re: [Brahms-dev-l] MrsT0 parameters

Hi Bjoern,
One can certainly check them in - as you have discovered it does in fact not
really matter since the
default constructor for the BrDetectorparamsMrsT0 sets the values used just
fine.
The parameters setup should match those in the constructor, and those read
in.
Do also note that since this was copied from BB there are some unused
parameters that could be taken out. One important parame is fSlatlenght !!

The #8 tubes do not refer to the number of slats in front of tpm1 there are
6 with the two
extra ones for the moveable calibration slat. the reason the 8 is kept is
mainly because this param is
used by supermon.
