The Chandra Multiwavelength Project:Galactic Plane Survey Chandra X-ray Observatory National Optical Astronomy Observatory

The ChaMPlane survey is being conducted at the Harvard-Smithsonian Center for Astrophysics.

Selection Criteria for ChaMPlane Chandra fields

The following are the criteria used to select ChaMPlane target fields from Chandra fields.
  • Chandra pointings with ACIS-I, ACIS-S or HRC imaging (TE) mode; no gratings, no CC mode.
  • Galactic plane fields ( |b| ~< 10 degree)
  • Deep Chandra fields (~>20 ksec)
  • Fields without bright (point or diffuse) X-ray and optical sources or background
  • Relatively low NH.
