EZmock
${DESI_ROOT}/survey/catalogs/{RELEASE}/mocks/EZmock hosts 1000 EZmock LSS mock catalogs (and associated random catalogs), separated by {OBSCON}: DARK or BRIGHT and followed by an internal version (both v1 for DARK and BRIGHT).
From the landing page, you will find 1000 directories called mock{MOCKREA} where {MOCKREA} is the mock realization from [1,1000].
Here you can find one mock flavour:
FFA (Fast Fiber Assigment): estimates fiber assigment probabilistically by learning from the data, based on number of passes and local density. These catalogs are stored under each
mock{MOCKREA}directory.
Detailed information about the content and production of these LSS mock catalogs is available in Ross et al. (2025)
