lss

$DESI_ROOT/vac/RELEASE/lss contains LSS catalogs reading from most other DESI products, ready for archiving with the early data release. Intermediate files are saved, until we build the clustering-ready catalogs (including weights).

VERSION contains different possible versions of the LSS catalogs, given a production run and a tile selection. As of the EDR release date, there is one single version named v2.0 (we use v2.0 in order to distinguish these catalogs from an internal DESI earlier v1.0 version).

The final clustering-ready catalogs can be found under LSScats/clustering, together with the random samples for the same target types. Information about the different target types and the use of the different weights can be found in EDR. DESI Collaboration (in prep.) and in the explanation of LSScats subdirectory.

The catalogs are generated using tools from github_lss_repository. For EDR we use the github release tag v2.0.0-EDR
