Galaxy catalogs:

data format:

column 1: galaxy ID
column 2: ra
column 3: dec
column 4: redshift
column 5: luminosity
column 6: i-band absolute magnitude
column 7: redshift error

----------------------------------------------

Group catalogs:

data format:

column 1: group ID
column 2: richness
column 3: ra
column 4: dec
column 5: redshift
column 6: log M_h/(M_sun/h)
column 7: L_group (10^10Lsun/h/h) 
column 8: f_edge; edge effect: See Yang et al. 2007

----------------------------------------------

member galaxy files:

1. The galaxies are listed in `iCLAUDS_HSC_1' with format:
     1. galaxy ID; 
     2. group ID; 
     3. brightest galaxy = 1; other galaxies in groups = 2 - i-band
     4. auxiliary ID, not used.
   
2. The group members are listed in `iCLAUDS_HSC_2' with format:
     1. group ID; 
     2. member galaxy ID in the galaxy catalog

----------------------------------------------

Protocluster candidates catalogue:

Protocluster candidates in three redshift bins: 2 <= z < 3, 3 <= z < 4 and z >= 4, referred as samples S1, S2 and S3 respectively.

1. The protocluster candidates are listed in `PC_S?' with format:

column 1: Protocluster candidates ID
column 2: group ID for central group
column 3: ra
column 4: dec
column 5: redshift
column 6: N_nei; total number of neighboring galaxies 
column 7: log M_nei/(M_sun/h); total halo mass of the neighboring groups

2. The neighboring galaxies are listed in `iPC_gal_S?' with format:

column 1: Protocluster candidates ID
column 2: galaxy ID for neighboring galaxies 

*** The neighboring galaxies or groups are searched around each central groups of protocluster candidates within a projected radius and a redshift difference less than 0.1. (see more details in Li et al. 2022)
