mockDESIDR9sv3_9tian: mock galaxy catalog in the redshift range z<1.0, and m_z<=21.0.

data format of the mock galaxy catalog:
(1) halo ID
(2) subhalo ID (0=central)
(3) subhalo trackID
(4) ra
(5) dec
(6) r (real space comoving distance, Mpc/h)
(7) z_cos
(8) z_obs (with RSD)
(9) snapshot number of the simulation
(10) host halo mass (log Msun/h)
(11) apparent magnitude in z-band (use this to make the test, here you can apply the average k-correction)
(12) subhalo maximum mass
(13) luminosity with K-correction.
