Abstract:
We present the first all-sky catalogue of galaxy clusters and cluster
candidates obtained from joint X-ray-SZ detections using observations
from the Planck satellite and the ROSAT all-sky survey (RASS). The
catalogue contains 2323 objects and has been validated by careful
cross-identification with previously known clusters. This validation
shows that 1597 candidates correspond to already known clusters, 212
coincide with other cluster candidates still to be confirmed, and the
remaining 514 are completely new detections. With respect to Planck
catalogues, the ComPRASS catalogue is simultaneously more pure and
more complete. Based on the validation results in the SPT and SDSS
footprints, the expected purity of the catalogue is at least 84.5%,
meaning that more than 365 clusters are expected to be found among the
new or still-to-be-confirmed candidates with future validation efforts
or specific follow-ups.
Description:
ComPRASS catalogue:
This catalogue was obtained from Planck and RASS surveys, using a
joint X-ray-SZ detection method. The details of its construction can
be found in Section 2 of the paper.
mask_comprass.fits:
This fits file respresents the mask used for constructing the ComPRASS
catalogue The map is in Healpix format, with nside=4096 resolution,
and "ring" ordering.
A value of "1" indicates that the position is not masked.
A value of "0" indicated that the position is masked.
Note: This map has been constructed by applying the masking criteria
used for ComPRASS to the center of each healpix pixel. As a result, in
the frontiers between masked and not masked zones, the sky positions
which are not exactly in the center of one of the pixels, may not be
exact. To obtain the exact mask, the criteria defined in Sect. 3.4.1
and 3.4.2 of Tarrio et al. (2018A&A...614A..82T 2018A&A...614A..82T) should be applied.
rasshealpixcountsec.fits:
This fits file contains the ROSAT all-sky survey (RASS) countrate map
in counts/second. The map is in Healpix format, with nside=4096
resolution, and "ring" ordering.
The countrate [counts/second] is obtained from the RASS counts in HARD
band and RASS exposure time, as explained in Appendix B1 of Tarrio et
al. (2016A&A...591A..39T 2016A&A...591A..39T). The value -1.63750e+30 indicates that there
is no information on the countrate (exposure time equal to 0).
