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.
