The gMOSS: the galaxy survey and galaxy populations of the large
  homogeneous field
  We present the gMOSS (Galaxies of Medium-band One-meter Schmidt telescope
Survey) catalog of $\sim$ 19,000 galaxies in 20 filters (4 broadband SDSS and
16 medium-band filters). We observed 2.386 $\mathrm{deg^2}$ on the central part
of the HS47.5-22 field with the 1-m Schmidt telescope of the Byurakan
Astrophysical Observatory. The gMOSS is a complete flux-limited sample of
galaxies with a threshold magnitude of $r$ SDSS $\le$ 22.5 AB. From photometric
measurements with 16 medium-band filters and $u$ SDSS, we get spectral energy
distributions for each object in the field, which are used for further
analysis. Galaxy classification and photometric redshift estimation based on
spectral template matching with ZEBRA software. The obtained redshift accuracy
is $\sigma_\mathrm{{NMAD}} < 0.0043$. Using the SED-fitting CIGALE code, we
obtained the main properties of the stellar population of galaxies, such as
rest-frame $(u - r)_{\mathrm{res}}$ colour, stellar mass, extinction, and
mass-weighted age with a precision of $0.16 \pm 0.07$ mag, $0.14 \pm 0.04$ dex,
$0.27 \pm 0.1$ mag, and $0.08 \pm 0.04$ dex, respectively. Using a
dust-corrected colour-mass diagram, we divided the full sample into populations
of red and blue galaxies and considered the dependencies between stellar mass
and age. Throughout cosmic time, red sequence galaxies remain older and more
massive than blue cloud galaxies. The star formation history of a complete
subsample of galaxies selected in the redshift range $0.05\le z\le0.015$ with
<$\mathrm{log} M \mathrm{>}_\mathrm{[M_\odot]}$>8.3 shows an increase in the
SFRD up to $z\sim3$, under the results obtained in earlier studies.
