CSCSTACKOB - Chandra Source Catalog Stacked Source Per-Observation Detections, v2.2 |
HEASARC Archive |
Overview
The Chandra Source Catalog (CSC) Per-Observation Detections Table includes 1,433,096 detections (and 2,536,232 detections and upper limits) from 17,879 observations. Extracted properties are provided for these individual observation detections identified in Chandra ACIS and HRC-I imaging observations released publicly through the end of 2024. Photometric properties for 1,821 highly extended (>30") sources are included as an "alpha" release, together with surface brightness polygons for several contour levels. This catalog is related to the CSC Stacked Observation Detections Table (CSCSTACK), which includes 527,230 detections (and 960,929 detections and photometric upper limits) based on 11,317 X-ray observations stacks.The Per-Observation Detections Table records the properties extracted separately from each observation included in the observation stack for each stacked-observation detection. Because a stack may include multiple observations, this table may contain multiple entries corresponding to a single entry in the Stacked Observation Detections Table. This and the Stacked Observation Detections Table (CSCSTACK) report several observation- and stack-specific properties, respectively, such as pointing and instrument information, that are common for all detections identified in that observation/stack.
This catalog and CSCSTACK are related to the Chandra Source Catalog, which is the definitive catalog of X-ray sources detected by the Chandra X-ray Observatory, and contains 407,806 unique compact and extended X-ray sources. By combining Chandra's sub-arcsecond on-axis spatial resolution and low instrumental background with consistent data processing, the CSC delivers a wide variety of uniformly calibrated properties and science ready data products for detected sources over four decades of flux.

This database table was last updated by the HEASARC in November 2026 and is based on a download of the online version of the "Per-Observation Detections" table, version 2.2, at the CXC using the CLI. Refer to https://cxc.harvard.edu/csc/cli/ for details.Links to Related CSC Tables
Chandra Source Catalog, v2.2 (CSC): The master sources table includes measured properties for 432,713 unique compact and extended X-ray sources in the sky. By combining Chandra's sub-arcsecond on-axis spatial resolution and low instrumental background with consistent data processing, the CSC delivers a wide variety of uniformly calibrated properties and science ready data products for detected sources over four decades of flux.Chandra Source Catalog Master Source-Stacked Source Associations, v2.2 (CSCASSOC) maps the master sources table CSC records to their associated stacked observation detections in CSCSTACK, and it also identifies the type of linkage (unique, ambiguous, or non-detection) that associates the two.
Chandra Source Catalog Stacked Observation Detections, v2.2 (CSCSTACK) includes 527,230 detections (960,929 total entries consisting of detections plus photometric upper limits) based on 11,317 stacks of X-ray observations. Exploiting the unique resolution and very low background of Chandra data, the limiting sensitivity of the catalog is enhanced significantly by stacking (co-adding) multiple observations of the same field prior to source detection.
Chandra Source Catalog Stacked Source-Observation Source Associations, v2.2 (CSCSTOBAS) maps the stacked observation detections table (CSCSTACK) records to their associated per-observation data in (CSCSTACKOB).
