- Discussed whether Difference Imaging Pipeline (Level 1) had products that could withstand compression.
- Discussed what additional resources might best help get this effort rolling (names have been redacted).
- Further discussion of tests that need to be performed.
- Image (compressed vs. uncompressed) comparison thought to be of only marginal use.
- Catalog level comparison should compare, position, mag/flux density, size/shape (and existence). It is thought that Princeton QA effort may have most of this already (and should inform item 2).
- May also need comparison of PSF products.
Action items
- Krzysztof Findeisen will look into both pipeline products and their downstream use (e.g. whether they are re-used for forced photometry
- Robert Gruendl try to round up more help
