A catalog of galaxy clusters identified from SCUSS, SDSS, and unWISE
  This paper presents the identification of galaxy clusters from the
photometric redshift catalog based on three imaging surveys of SCUSS, SDSS, and
unWISE. By applying a fast clustering algorithm, we obtain a total of 19,610
clusters in the redshift range of $0.05 < z < 0.65$ over a sky area of about
3,700 deg$^2$ in the south Galactic gap. Monte Carlo simulations show that the
false detection rate is about 8.9\%. The redshift uncertainty is estimated to
be about 0.013. The mass and richness of detected clusters are derived through
the calibration based on the measurements of X-ray emission and
Sunyaev--Zel'dovich effect.
