Query: A catalogue of clusters of galaxies identified from all sky surveys of
  2MASS, WISE, and SuperCOSMOS   We identify 47,600 clusters of galaxies from photometric data of Two Micron
All Sky Survey (2MASS), Wide-field Infrared Survey Explorer (WISE), and
SuperCOSMOS, among which 26,125 clusters are recognized for the first time and
mostly in the sky outside the Sloan Digital Sky Survey (SDSS) area. About 90%
of massive clusters of M_{500}>3*10^{14} M_{\odot} in the redshift range of
0.025<z<0.3 have been detected from such survey data, and the detection rate
drops down to 50% for clusters with a mass of M_{500}~1*10^{14} M_{\odot}.
Monte Carlo simulations show that the false detection rate for the whole
cluster sample is less than 5%. By cross-matching with ROSAT and XMM-Newton
sources, we get 779 new X-ray cluster candidates which have X-ray counterparts
within a projected offset of 0.2 Mpc.
