1SXPS Swift X-ray telescope point source catalogue
Listed in IVOA Registry (Virtual Observatory)
We present the 1SXPS (Swift-XRT Point Source) catalogue of 151,524 X-ray point-sources detected by the Swift-XRT in 8 years of operation.
Description
The catalogue covers 1905 square degrees distributed approximately uniformly on the sky. We analyze the data in two ways.
First we consider all observations individually, for which we have a typical sensitivity of ~3e-13 erg.cm^-2^s^-1` (0.3-10 keV). Then we co-add all data covering the same location on the sky: these images have a typical sensitivity of ~9e-14 erg cm^-2^s^-1^ (0.3-10 keV). Our sky coverage is nearly 2.5 times that of 3XMM-DR4, although the catalog is a factor of ~1.5 less sensitive.

The median position error is 5.5" (90% confidence), including systematics. Our source detection method improves on that used in previous XRT catalogues and we report >68,000 new X-ray sources. The goals and observing strategy of the Swift satellite allow us to probe source variability on multiple timescales, and we find ~30,000 variable objects in our catalog.
For every source we give positions, fluxes, time series (in four energy bands and two hardness ratios), estimates of the spectral properties, spectra and spectral fits for the brightest sources, and variability probabilities in multiple energy bands and timescales.
