DM-2984, we are confident that the ISR performed by the LSST and HSC stacks is equivalent. Extend that work to cover the whole of single-frame processing (ProcessCcdTask).
There are two deliverables for this issue:
- A collections of plots and/or comparison scripts that run on the pipeline outputs that can be used to compare their quality in all the ways we think matter. This should probably be in a new repo. Some of these tests should compare the results of the two pipelines against each other (as that's easier to do), but others should be useful for tracking the quality of the pipeline even after we abandon the HSC fork.
- A set of new JIRA issues that capture the code transfers we think we will need to get the LSST pipeline up to the same level of quality as the HSC one.
