================================ The "full" LSS catalogs for data ================================ :Summary: LSS catalogs containing information on all targets identified as reachable by DESI fiberassign, with one entry for each. The files are split by target type and whether of not vetos for angular positions have been applied. :Naming Convention: ``{TARGET}_full{VETO}.dat.fits``, where ``{TARGET}`` is the target type: ``QSO``, ``ELG``, ``ELGnotqso``, ``ELG_HIP``, ``ELG_HIPnotqso``, ``LRG``, ``LRG_main``, for dark or ``BGS_ANY``, ``BGS_BRIGHT`` for bright. ``{VETO}`` is _noveto if vetos have not been applied and blank otherwise :Regex: ``[a-zA-Z_]+\_full[a-z_]{0,7}.dat.fits`` :File Type: FITS, 1 GB (size varies considerably depending on target type) Contents ======== ====== ======= ======== =================== Number EXTNAME Type Contents ====== ======= ======== =================== HDU0_ IMAGE Empty HDU HDU1_ LSS BINTABLE Catalog data ====== ======= ======== =================== FITS Header Units ================= HDU0 ---- This HDU has no non-standard required keywords.
