      Description

      When Meredith Rawls ran DcrAssembleCoaddTask it failed on patches with large regions of no data. The Task should test whether subregions contain data at an earlier stage, and skip them or fail earlier. See the log below for an example:

      ==> slurm/job146732-24.out <==
          res = func(self, *args, **keyArgs)
        File "/project/mrawls/pipe_tasks/python/lsst/pipe/tasks/dcrAssembleCoadd.py", line 233, in runDataRef
          results = AssembleCoaddTask.runDataRef(self, dataRef, selectDataList=selectDataList)
        File "/software/lsstsw/stack_20181012/stack/miniconda3-4.5.4-fcd27eb/Linux64/pipe_base/16.0-16-ge6a35c8+5/python/lsst/pipe/base/timer.py", line 149, in wrapper
          res = func(self, *args, **keyArgs)
        File "/project/mrawls/pipe_tasks/python/lsst/pipe/tasks/assembleCoadd.py", line 361, in runDataRef
          inputData.weightList, supplementaryData=supplementaryData)

          convergenceCheck = (convergenceList[-1] - convergenceMetric)/convergenceMetric
      ZeroDivisionError: float division by zero
