The .tar file are named in terms of the band name and the year when the exposures are taken. 

The definitions of the columns in each catalog file are the following :

(# RA Dec z_zou z_zou_err z_rongpu z_s nstar SNR_F  gf1 gf2 g1 g2 de h1 h2)

RA, Dec: galaxy position;

z_zou, z_zou_err: the redshift measured by Zou Hu and its error;

z_rongpu: the redshift measured by Zhou Rongpu;

z_s: the spectral redshift;

nstar: the number of stars in the chip of the galaxy image;

SNR_F: the signal-to-noise ratio measured in Fourier space;

gf1, gf2: the shear induced by field distortion (as an indication of the galaxy position on the focal plane);

g1, g2, de, h1, h2: the shear estimators defined in Fourier_Quad method.
