NGC 2362 Chandra X-Ray Point Source Catalog NGC2362CXO ivo://nasa.heasarc/ngc2362cxo NASA/GSFC HEASARC Damiani et al. 2026-10-09 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source This table contains the results of an observation of the young cluster NGC 2362 in X-rays with Chandra ACIS-I in which 387 point X-ray sources, most of which are shown to be cluster members, were detected using PWDetect, a wavelet-based source detection algorithm, with a detection threshold chosen to ensure no more than one spurious detection in the entire ACIS FOV. The table lists all of the detected X-ray sources and their basic X-ray properties, as well as their proposed identifications with optical stars, using data from Moitinho et al. (2001ApJ...563L..73M; UBVRI photometry) and Dahm (2005, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/AJ/130/1805"&gt;CDS Cat. &lt;J/AJ/130/1805&gt;&lt;/a&gt;; H-alpha data), as well as newer photometric data from Moitinho et al. (2005, in &#39;Cores to Clusters&#39; [A&amp;SSL, 324], 167). A matching position of less than 4 times the X-ray positional uncertainty of the X-ray source from PWDetect was used. Also included in the table is a classification of the optically-identified X-ray sources, based on their positions in the HR Diagram, which helps to separate rather clearly the cluster members from interloping field objects. This table was created by the HEASARC in March 2007 based on CDS table J/A+A/460/133 files table2.dat and table3.dat.
