meaning of different columns in the output fits file of fiberassign

[zhengyun0215]

Hi all ！ We are trying to run mocks for SV3 . By using fba_run for our mock catalogue, we get outputs like “fba-000012.fits” . We want to figure out the meaning of each column to understand these output files in detail so that we can use some methods to test the fiber-collision effects . We found https://desidatamodel.readthedocs.io/en/latest/DESI_TARGET/fiberassign/tile-TILEID-FIELDNUM.html#hdu5 this page describes the fba outputs ,but it seems outdated . For example , it just mentions ‘FIBERSTATUS’ as Fiber status mask; 0=good but we got some other numbers . Some other columns like ‘FA_TYPE’ and ‘FA_TARGET’ are Description needed …. Do you know if there are any documents describing these columns in detail or where we can find some files like Fiber status mask so that we can figure out which fiber couldn't work properly because of fiber collision ? Thank you so much 😊
