      Description

      DcrAssembleCoaddTask produces several warnings when run, which are harmless but distracting. These should either be fixed or silenced.

       

      Examples:

      py.warnings WARN: /project/sullivan/code/pipe_tasks/python/lsst/pipe/tasks/dcrAssembleCoadd.py:1212: RuntimeWarning: invalid value encountered in true_divide
