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.

In EDR, 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). In DR1, there is one version named guadalupe/v1.0. This data should only be used to reproduce results from the early detection of the BAO signal presented in Moon et al. (2023). The main survey results from Data Releases are to be found in ../../catalogs/dr1/LSS directory.

For EDR and DR1 Guadalupe, 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 et al. (2024) and Appendix A in DR1. DESI Collaboration et al. (2025) submitted

Further information is also found in LSScats subdirectory. The catalogs are generated using tools from github_lss_repository. For EDR we use the github release tag v2.0.0-EDR
