The 400d cluster Survey
Listed in IVOA Registry (Virtual Observatory)
We present a catalog of galaxy clusters detected in a new ROSAT PSPC survey.
Description
The survey is optimized to sample, at high redshifts, the mass range corresponding to T>5keV clusters at z=0. Technically, our survey is the extension of the 160 square degree survey (160d, Cat.
J/ApJ/502/558). We use the same detection algorithm, thus preserving high quality of the resulting sample; the main difference is a significant increase in sky coverage. The new survey covers 397deg^2^ and is based on 1610 high Galactic latitude ROSAT PSPC pointings, virtually all pointed ROSAT data suitable for the detection of distant clusters.

The search volume for X-ray luminous clusters within z<1 exceeds that of the entire local universe (z<0.1). We detected 287 extended X-ray sources with fluxes f>1.4x10^-13^ergs/s/cm^2^ in the 0.5-2keV energy band, of which 266 (93%) are optically confirmed as galaxy clusters, groups or individual elliptical galaxies.
