Abstract:
We present a catalog of galaxy clusters detected in a new ROSAT PSPC
survey. 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
397deg2 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>1.4x10-13ergs/s/cm2
in the 0.5-2keV energy band, of which 266 (93%) are optically
confirmed as galaxy clusters, groups or individual elliptical
galaxies.
Description:
The 400d survey is based on the ROSAT PSPC pointed observations
selected from the archive by the following criteria: (1) Galactic
latitude |b|>25°, (2) Galactic absorption NH<1021cm-2,
(3) total clean exposure texp>1000s, and (4) targeted at least
10° away from the LMC and SMC. The final set contains 1610 fields,
including all data from the 160d survey (except the pointing toward
Arcturus) plus 964 additional fields.

within |Δz|<0.01 of the ROSAT target redshift are listed
separately in Table 5 because they are not entirely serendipitous.
