Abstract:
This catalogue contains 2356 entries. It was created to list targets
of interest that have similar near- and mid-infrared characteristics
than R Coronae Borealis (RCB) stars which are hydrogen-deficient
carbon-rich supergiant stars known to possess warm circumstellar
shells. It is therefore a catalogue enriched in such objects and
further spectroscopic follow-ups are needed to reveal the true nature
of each target.
The catalogue was produced from a series of selection criteria on the
infrared colours and brightness of sources published in the WISE
All-Sky data release, and also listed in the 2MASS catalogue. These
sources spread over the entire sky. The selection criteria are
described in section 2 of the paper.
Description:
For each object, there are 23 informations listed. Firstly, the
identification number of each target of interest, ranging from 1 to
9999 is given followed by the unique WISE All-Sky catalogue source
designation. Secondly, we list the equatorial and Galactic
coordinates, followed by all four WISE All-Sky (Wright et al.,
2010AJ....140.1868W 2010AJ....140.1868W) and three 2MASS (Skrutskie et al., 2006, Cat.
VII/233) magnitudes with their related 1-sigma errors. If one
magnitude was not available, its value was replaced by the number -99.
Thirdly, in the last three columns, the catalogue report informations
found in the SIMBAD database as of August 2015, using a 3 arcsec
matching radius. They are the name, the object type and the spectral
classification. If such data did not exist, the number -99 was given
instead, in replacement. WISE data acquisition and reduction are
discussed in Wright et al. (2010AJ....140.1868W 2010AJ....140.1868W) and in the
Explanatory Supplement to the WISE All-Sky Data Release Products. The
[4.6] band magnitudes were corrected if brighter than 6.35mag to
correct a bias due to the wing PSF-fitting in this saturation regime
(See Sect. 2.1 of the paper).
