testdata_image_cutouts is a package in the LSST Science Pipelines.
This package contains a butler repo with a three coadd images for testing the image cutouts service.
Contains bands gri for tract=3828 and patch=24 with skymap="DC".
Use collection="2.2i/runs/test-med-1/w_2022_03/DM-33223/20220118T193330Z" to read the deepCoadd_calexp data.
The images have been recompressed with fpack lossy Rice compression, to reduce the size of the repo (we don't actually care about preserving original pixel values here).
A clone of this repo takes up about 300MB of space.
To reproduce the data with a new weekly run of DC2, update the collection value in scripts/export_dc2_subset.py, run these commands from the root of this package on lsst-devl:
rm -r repo/ python scripts/export_dc2_subset.py bash scripts/make_dc2_subset_repo.sh
In order for the butler datastore file integrity check to pass, change the file_datastore_records table in repo/gen3.sqlite3 to set all three file_size fields to -1.
Test out the new data, and then commit the updated scripts, dc2-exports.yaml file, and repo directory (check that all relevant large files are using git-lfs).
