High-z Mock Samples for zCOSMOS and Subaru/PFS
The catalogs are constructed by Meng et al. 2020 for high-z galaxy redshift survey. For any problem in the data or data accessing, please email to Jiacheng Meng (mengjc18@mails.tsinghua.edu.cn).
For completeness, we also include the real zCOSMOS-bright sample and its random sample.
In the below, we list the catalogs that can be downloaded and we give a description of the catalogs. A markdown version [README.md] can be saved.

Introduction to the High-z Catalogs
zCOSMOS-bright Mock
The files are the mocks for the zCOSMOS bright sample. The selection criteria is $I < 22.5$.
The file name is zc_i.fits, where the "i" indicates the i-th mock. We totally generate 20 mock catalogs.
The columns in the file are
- ID : the id of the galaxy.
- gID : the id of the group the galaxy is in.
- ra .
- dec .
- z : redshift.
- stellar_mass : the mass of the galaxy, the unit is $ \log_{10}(M_*/M_\odot) $.
- m_B : B-band apparent magnitude.
- m_I : I-band apparent magnitude.
- M_B : B-band absolute magnitude.
- M_I : I-band absolute magnitude.
- snap : the snap-shot of the galaxy in the simulation.
- halo_mass : the mass of the halo the galaxy in, the unit is $ 10^{10} M_\odot/h $.
- source_tag : 1 for central galaxies and 0 for satellites.
- survey_tag : 1 for galaxies satisfying the selection criteria and 0 for not.
- TSR : 1 for galaxies are observed and 0 for not.
- SSR : 1 for galaxies with successful redshift measurement and 0 for not.
zCOSMOS-bright Real Sample
The galaxy catalog and random sample catalog for the zCOSMOS-bright sample.
zcosmos_sample.fits: zCOSMOS-bright galaxy sample. It is secure to use the galaxies with Flag==1 and in the central region. That is (Flag == 1) & (Center_region == 1).
- ID : the id of the galaxy.
- RA : J2000.
- Dec : J2000.
- ID_2015 : ID in COSMOS2015 catalog.
- z_spec : spectroscopic redshift.
- Type : 0 for galaxies; 1 for stars; 2 for X-ray sources.
- Mass : stellar mass, unit: $M_\odot$.
- Flag : 1 for well matched galaxies with secure redshift.
- CC : confidence class of spectroscopic redshift (Lilly et al. 2009).
- Weight : weight for each galaxy.
- Center_region : 1 for galaxies in the central region of zcosmos survey $\rm 149.62 < RA < 150.61$ and $\rm 1.75 < Dec < 2.70$.
- m_I : apparent magnitude of I band (HST 814W).
- M_I : absolute magnitude of I band (HST 814W).
- M_B : absolute magnitude of B band.
zcosmos_random.fits : The random sample for the zCOSMOS-bright sample. The redshift range is 0.1~1.5. It only contains the points in the central region.
- RA : J2000.
- Dec : J2000.
- z : redshift.
- Mass : stellar mass, unit: $\log(M_*/M_\odot)$.
- m_I : apparent magnitude of I band (HST 814W).
- M_I : absolute magnitude of I band (HST 814W).
