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
).
