### Group catalog ###
Filename: Data/SDSS_group_z12Cor_XYZ.dat
Col_Num   Name
1:        Mass of the group
2-4:      3d cartesian coordinates of the group (unit of Mpc/h, MW is at 0,0,0) in J2000 system.
Note that the redshift distortion (Kaiser effect) has been corrected.


### Galaxy catalog ###
Filename: Data/SDSS7_z12Cor_xyz2
Col_Num   Name
1:        Mr-5logh, absolute magnitude in r band
2-4:      3d cartesian coordinates (x, y, z)

Filaname: Data/SDSS7_z12Cor_pro
Col_Num   Name
1:        Mr-5logh, absolute magnitude in r band
2-3:      ra and dec in the J2000 spherical coordinate
4:        redshift corrected by taking into account Kaiser effect
5:        g-r, galaxy color

### Simulation data ###
Simulation data and halo catalog will be supplemented soon!
