- Dark matter halo ID, as taking from the simulation
-
* - :code:`loghalom`
- logarithmic value of the DM's mass
- log(Msun/h) where h=1
* - :code:`halo_ngal`
- Total number of galaxies in DM halo. Number of galaxies in the
mock may differ from this value
-

- km/s
* - :code:`vel_tan`
- Tangential component of the peculiar velocity
- km/s
* - :code:`morph`
- Galaxy's morphology. 'LT': *Late Type*; 'ET': *Early type*. Used either *goodmorph* (ECO) or *MORPH* (RESOLVE) keys. '-9999' if no matched galaxy
-
* - :code:`logmstar`
- Log value of galaxy's stellar mass. Used either '*rpgoodmstarsnew*' (ECO) or '*MSTARS*' (RESOLVE) keys in the files
- log(Msun)
* - :code:`rmag`
- r-band *apparent* magnitude. Used either 'rpsmoothrestrmagnew' (ECO) or '*SMOOTHRESTRMAG*' (RESOLVE) keys in the files.
- magnitudes
* - :code:`umag`
- u-band *apparent* magnitude. Used either 'rpsmoothrestumagnew' (ECO) or '*SMOOTHRESTUMAG*' (RESOLVE) keys in the files.
- magnitudes
* - :code:`fsmgr`
- Stellar mass produced over last Gyr divided by pre-existing stellar
mass from new model set. Used '*rpmeanssfr*' (ECO) or '*MODELFSMGR*'
(RESOLVE) keys.
- (1/Gyr)
* - :code:`survey_flag`
- Survey name, from which the properties of the **real** matched galaxy
were extracted.
-
* - :code:`u_r`
- Color of the matched galaxy, i.e. (:code:`umag` - :code:`rmag`)
- magnitudes
* - :code:`mhi`
- HI mass in galaxy. Used the *predicted* HI massed (matched to the ECO
file, i.e. :code:`eco_wresa_050815.dat`) and the key '*MHI*' (RESOLVE).
To compute MHI masses using *ECO*, we used the formula
:math:`10^(:code:`MHI` + :code:`logmstar`)`
- Msun
* - :code:`groupid`
- Group ID, to which the galaxy belongs after running *Berlind2006* FoF group finder.
-
* - :code:`g_ngal`
- Number of galaxies in a group of galaxies
-
* - :code:`halo_rvir`
- Virial radius of the DM halo, to which the galaxy belongs.
- Mpc/h with *h* = 1.
* - :code:`M_group`
- Abundance matched mass of the galaxy group. This was calculated by
assuming a monotonic relation between DM halo mass :code:`logM_halo`
and the group *total* luminosity. For RESOLVE-B, we used a modified
version of the *ECO* group luminosity function.
- Msun/h with *h* = 1
* - :code:`g_galtype`
- Type of galaxy. **Group central** = 1, **Group satellite** = 0

.. note::

The relationship between velocities (:code:`cz`'s') is the following:
:math:`(:code:`cz` - :code:`cz_nodist`)^2 + (vel_tan)^2 = (vel_tot)^2`.
