Description
The ChaMPlane survey of the galactic plane ( ~100 ACIS fields over 5
years, selected for exposure at least ~20ksec, galactic latitude below
~10deg, and minimum column density NH), will provide the largest sample
of faint galactic x-ray sources. The arcsec positions for most of these
will allow unambiguous optical identifications from our NOAO Long Term
Survey program and measurement of source properties to enable new
constraints on the galactic populations of accretion-powered white
dwarfs, neutron stars and black holes as well as stellar coronal x-ray
sources. Here we provide initial results on the x-ray source properties
for the first 10 fields (for which archival data are available). We
present x-ray fluxes, x-ray colors (from Soft, Medium and Hard bands)
and detected source distributions for an initial assessment of the
likely populations being seen. Optical identifications are presented for
sources in several example fields (and see paper by Zhao et al) to
provide an initial calibration and investigation of the x-ray/optical
flux vs. color relations. This work is supported by NASA/SAO grant
AR1-2001X and NSF grant AST-0098683.
