Chandra Orion Ultradeep Point Source Catalog
Listed in NASA Data Portal
The Chandra Orion Ultradeep Project (COUP) was a deep observation of the Orion Nebula Cluster (ONC) that was obtained with the Chandra X-Ray Observatory's Advanced CCD Imaging Spectrometer (ACIS).
Description
This Browse table contains the COUP catalog of more than 1600 X-ray point sources that were detected in the exceptionally deep 2003 January observation, which was an 838 ks exposure made over a continuous period of 13.2 days.
The COUP observation provides the most uniform and comprehensive data set on the X-ray emission of normal stars ever obtained in the history of X-ray astronomy. This table was created by the HEASARC in September 2006 based on the <a href="cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/160/319">CDS catalog J/ApJS/160/319</a>, tables 2, 4, 6, 7, 8, 9, and 10. This is a service provided by NASA HEASARC .
