DECam Exclude Lists

Assemble lists of bad/suspect DECam images to exclude from high-level processing. These lists are collected using a number of techniques including an automated ray-tracing procedure and visual inspection. These lists follow the same format as the DES exclusion lists found here.

Execution

Create pngs of the problem exposures:

./bin/run_png.sh

Assemble the webpages:

./bin/run_www.sh

Compile the list of excluded CCD images (expnum/ccdnum) where YYYYMMDD is the current date:

python bin/make_exclude_list.py y*/*.txt -o delve_exclude_YYYYMMDD.fits

Upload list to the DESDM Oracle database:

easyaccess -s decade -lt delve_exclude_YYYYMMDD.fits
easyaccess -s decade -c "grant select on DELVE_EXCLUDE_YYYYMMDD to PUBLIC;"

Usage

If you use this exposure list, please be sure to include a link to repository in your publication along with citations to DES (DES Collaboration 2016) and DELVE (Drlica-Wagner et al. 2021). Details on the automated ray-tracing technique used to identify ghosts and scattered light can be found in Kent (2013) and is described in some detail in (Chang et al. 2021).
