Subject: Proposal for smart event selection (AI30_18)
T

   Hi,

   here's a first attempt to define how 'smart' selection could
work. Comments are welcome, as usual:

* If radiusLimit > 0 it is used as a fixed cut on radius.
   Other selections are still applied as explained below,
   if the program has suitable parameters.

* radiusLimit < 0 is used as an alias for "try best selection".

* The following parameters are used to set which cases of bad
   events to ignore (based on j_src_spectra.par, new ones marked
   by #):

   skipDeadAnode,b,h,y
   skipNearDeadAnode,b,h,y
   skipHotSpot,b,h,y

   skipBadOBT,b,h,y      #
   skipBadGain,b,h,y     #

   These exclusions would then be encoded into a total STATUS flag
   for bitwise comparison.

   In my view, the other known problems flagged at the event level
   should always be skipped. Otherwise additional parameters would be
   needed.

* In addition to the above, I'd propose to allow to skip zones of
   high background. My problem is that I'm not quite sure how to best
   define them in an energy dependent fashion. I mean one could
   calculate the bkg flux per pixel in a given band and then make some
   sort of cut, but this could turn out to be heavy. Any ideas?


   regards,
   Peter
