## CSC - Chandra Source Catalog, v2.0 |
HEASARC Archive |

The extracted properties are provided for 928,280 individual observation detections, identified in 10,382 Chandra ACIS and HRC-I imaging observations released publicly through the end of 2014, at the Chandra X-ray Center. CSC 2.0 includes -- as an "alpha" release -- photometric properties for 1,299 highly extended (> ~30") sources, together with surface brightness polygons for several contour levels.

The sensitivity limit for compact sources in CSC 2.0 is ~5 net counts (a factor of >~2 better than the previous catalog release). This improvement is achieved by using a two-stage approach that involves co-adding multiple observations of the same field prior to source detection, and then using an optimized source detection method.

For each X-ray detection and source, the catalog provides a detailed set of more than 100 tabulated positional, spatial, photometric, spectral, and temporal properties (each with associated lower and upper confidence intervals and measured in multiple energy bands). The catalog Bayesian aperture photometry code produces robust photometric probability density functions (PDFs), even in crowded fields and for low count detections. Release 2 uses a Bayesian Blocks analysis to identify multiple observations of the same source that have similar photometric properties, and these are analyzed simultaneously to improve S/N.

The energy bands used to derive many of the CSC properties are defined in Table 4 of the reference paper: ultrasoft (u: 0.2-0.5 keV), soft (s: 0.5-1.2 keV), medium (m: 1.2-2.0 keV), hard (h: 2.0-7.0) and broad (b: 0.5-7.0 keV) for the ACIS energy bands, and wide (w: 0.1-10.0 keV) for the HRC energy band. The energy bands are chosen to optimize the detectability of X-ray sources while simultaneously maximizing the discrimination between different spectral shapes on X-ray color-color diagrams.

Numerous source-specific catalog properties are evaluated within defined apertures. The authors define the "PSF 90% ECF aperture" for each source to be the ellipse that encloses 90% of the total counts in a model PSF centered on the source position. Because the size of the PSF is energy-dependent, the dimensions of the PSF 90% ECF aperture vary with energy band. They define the "source region aperture" for each source to be equal to the corresponding 3-sigma source region ellipse included in the merged source list, scaled by a factor of 1.5. Like the PSF 90% ECF aperture, the source region aperture is also centered on the source position, but the dimensions of the aperture are independent of energy band.

**Name**

The Chandra Source Catalog name in the IAU position-based nomenclature, viz.,
'2CXO Jhhmmss.s{+,-}ddmmss', where the 'CXO' stands for Chandra X-ray
Observatory and the '2' stands for version 2 of this catalog.

**RA**

The Right Ascension of the X-ray source in the selected equinox. This was
given in ICRS coordinates in the original source table and was determined by
statistically averaging the positions of detections from the individual
stacked observations that are uniquely matched to the source. The calculation
of the averaged positions and position uncertainties is described in detail
in the How and Why topic 'Source Position Errors in the Master Sources Table'
at https://cxc.harvard.edu/csc/why/err_ellipse_msc.html.

**Dec**

The Declination of the X-ray source in the selected equinox. This was given
in ICRS coordinates in the original source table and was determined by
statistically averaging the positions of detections from the individual
stacked observations that are uniquely matched to the source. The calculation
of the averaged positions and position uncertainties is described in detail
in the How and Why topic 'Source Position Errors in the Master Sources Table'
at https://cxc.harvard.edu/csc/why/err_ellipse_msc.html.

**Error_Ellipse_R0**

The major radius of the 95% confidence level position error ellipse, in
arcseconds. The source position error ellipses in the Master Sources Table
include a component to account for the absolute uncertainty in the astrometry
relative to the ICRS reference frame. This uncertainty, 0.71 arcsec (95%
confidence) in each axis, is derived from comparisons of source positions
from release 2.0 detections relative to the Sloan Digital Sky Survey, and is
added in quadrature to the statistically averaged position uncertainties from
the stacked observation detections.

**Error_Ellipse_R1**

The minor radius of the 95% confidence level position error ellipse, in
arcseconds. The source position error ellipses in the Master Sources Table
include a component to account for the absolute uncertainty in the astrometry
relative to the ICRS reference frame. This uncertainty, 0.71 arcsec (95%
confidence) in each axis, is derived from comparisons of source positions
from release 2.0 detections relative to the Sloan Digital Sky Survey, and is
added in quadrature to the statistically averaged position uncertainties from
the stacked observation detections.

extended source, this flag is NULL.

observations for compact sources or in any observations for extended sources;
source properties may be affected.

**Sat_Src_Flag**

source properties are unreliable. For extended sources, this flag is NULL.

review.

**Man_Inc_Flag**

position input to the Maximum Likelihood Estimator fit) were manually
modified via human review.

overlapping stacked observations via human review, i.e. the observation
detections were not matched, or were matched incorrectly, by the detection
matching algorithm.

This is set to 'T' if the best fit source position was manually modified via
human review.
