=========================================================================== COSMOS XMM Data Version 3.0 =========================================================================== The Cosmic Evolution Survey (COSMOS) is an HST Treasury Project to survey a 2 square degree equatorial field, centered on RA=10:00:28.6 and DEC=+02:12:21.0, using the ACS camera. The project also incorporates major commitments from other observatories around the world, including the VLA radio telescope, ESO's VLT in Chile, ESA's XMM X-ray satellite, and the Japanese 8-meter Subaru telescope in Hawaii. XMM-Newton observed the COSMOS field for a total of 1.55 Ms (to an homogeneous X-ray flux limit of ~5e-16 cgs in the 0.5-2 keV band). The data present in the archive refer to the mosaic constructed with all the XMM observations (AO3+AO4+AO6, 55 "good" XMM pointings, ~1.55 Ms in total). The key characteristics of these data: Instrument: XMM European Photon Imaging Camera (EPIC) Dates of observations: AO3+AO4+AO6 (Dec 2003 - Jun 2007) Observing time: ~30 ksec / pointing Energy range: 0.5 - 10.0 keV Area: ~2 sq deg Resolution: 4"/pixel The data products available here include: (1) Three vignetted exposure maps, created from the original X-ray photon event files, filtered by photon energy: xmm_C0520-vigyes-w.exp 0.5 keV < e < 2.0 keV xmm_C2080-vigyes-w.exp 2.0 keV < e < 8.0 keV xmm_C4510-vigyes-w.exp 4.5 keV < e < 10.0 keV (2) Three background maps, created as described in Cappelluti et al. 2006: xmm_C0520.bg 0.5 keV < e < 2.0 keV xmm_C2080.bg 2.0 keV < e < 8.0 keV xmm_C4510.bg 4.5 keV < e < 10.0 keV (3) Three images, created from the X-ray photon event files, filtered by photon energy: xmm_C0520.img 0.5 keV < e < 2.0 keV xmm_C2080.img 2.0 keV < e < 8.0 keV xmm_C4510.img 4.5 keV < e < 10.0 keV (4) Six sensitivity maps created from the X-ray photon event files and exposure map, filtered by photon energy. These are divided in two sub-classes: -Units of the maps counts/s assuming a likelihood threshold, detml=10 xmm_C_0520-10.sens 0.5 keV < e < 2.0 keV xmm_C_2080-10.sens 2.0 keV < e < 8.0 keV xmm_C_4510-10.sens 4.5 keV < e < 10.0 keV -Units of the maps erg cm^-2 s^-1 assuming a likelihood threshold, detml=10 xmm_C_0520-10_fl.sens 0.5 keV < e < 2.0 keV xmm_C_2045-10_fl.sens 2.0 keV < e < 10.0 keV xmm_C_4510-10_fl.sens 5.0 keV < e < 10.0 keV Further information may be obtained from the XMM-COSMOS web page: http://www.mpe.mpg.de/xmmcosmos/Cosmos/ or the main COSMOS web page: http://cosmos.astro.caltech.edu/ =========================================================================== The COSMOS Team, Patrick Shopbell (Archive Lead), and Nico Cappelluti pls@astro.caltech.edu, cappelluti@xray.mpe.mpg.de June, 2008 pls@astro.caltech.edu
