cds-question@unistra.frx-ray-sourcesA deep X-ray survey of the Hubble Deep Field-North (HDF-N) and its environs is performed using data collected by the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra X-Ray Observatory. Currently a 221.9ks exposure is available, the deepest ever presented, and here we give results on X-ray sources located in the 8.6'x8.7' area covered by the Caltech Faint Field Galaxy Redshift Survey (the "Caltech area"). This area has (1) deep photometric coverage in several optical and near-infrared bands; (2) extensive coverage at radio, submillimeter, and mid-infrared wavelengths; and (3) some of the deepest and most complete spectroscopic coverage ever obtained. It is also where the X-ray data have the greatest sensitivity; the minimum detectable fluxes in the 0.5-2keV (soft) and 2-8keV (hard) bands are ~1.3x10^-16^ and ~6.5x10^-16^ergs/cm^2^/s, respectively.2001ApJ...554..742Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/554/742CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/124/2351 : Chandra Deep Field North survey.
