      Description

      50% KSK 50% RO A small amount of this work is in 02C.03.01
      The diffim task needs to be looked at. It needs to be updated to use current mechanisms. It should also be refactored to split out some of the procedural code into methods.

      In a similar task, the lsstSimIsrTask needs to include a real snap combine step. Currently, one of the snaps is dropped on the floor. For this round just implement naive snap addition and morphological CR rejection.

          While looking at DM-980 (converting ip_diffim to use meas_base), I ran across some suspicious looking code in src/DipoleAlgorithm.cc. Specifically, in NaiveDipoleFootprinter:

          184         if (ival >= 0.0) {
          		 
          185             _sumPositive += ival;
          		 
          186             _varPositive += vval;
          		 
          187             ++_numPositive;
          		 
          188         } else {
          		 
          189             _sumNegative += ival;
          		 
          190             _varPositive += vval;

          Should be _varNegative?

          195     double getSumPositive() const { return _sumPositive; }
          		 
          196     double getSumNegative() const { return _sumNegative; }
          		 
          197     double getVarPositive() const { return _sumPositive; }
          		 
          198     double getVarNegative() const { return _sumNegative; }

          Surely the last two should return _varPositive and _varNegative respectively?

          202 private:
          		 
          203     double _sumPositive;
          		 
          204     double _sumNegative;
          		 
          205     double _varPositive;
          		 
          206     double _varNegative;

          _varNegative is never used.

          I've not attempted to understand the algorithm, so the above could all be intentional (but strange); furthermore, it may be this code will all be scrapped and replaced as part of this epic. However, I wanted to record these issues somewhere to make sure they aren't forgotten.

          Finishing the work involved in refactoring will be undertaken DM-14450.
