mockG1: the mock galaxy catalog based on Guo Hong's input galaxy catalog with setllar mass.
-- redshift <0.5, with the skycoverage of DESI LS DR9

mockGL1: similar to the above but for redshift 0.5<=z<1.0

data format:
col1: galaxy ID (starting from 1)
col2: subhallo ID
col3: host halo ID
col4: 0 -- not used
col5: ra in degrees
col6: dec in degrees
col7: comoving redshift
col8: observed redshift
col9: z-band apparent magnitude
col10: z-band magnitude limit
col11: completness
col12: log stellar mass
col13: log halo mass
col14: z-band absolute magnitude

==============================================

mockG1_obs: mock galaxy matched with DESI observation.

data format:
col1: redshift
col2: luminosity
col3: halo mass
col4: DESI ra
col5: DESI dec
col6: DESI redshift
col7: DESI luminosity
col8: DESI group mass

==============================================

randGS1: the random galaxy sample, in the same format as mockG1.
randGL1: the random galaxy sample, in the same format as mockGL1.
