Descripción
Chandra X-ray Observatory has unprecedented spatial resolution and
sensitivity. Its 0.5 arcsec on-axis PSF provides for the first time an
angular resolution comparable to ground based optical telescopes. Thus
the serendipitous sources in each Chandra field constitute a rich
collection of previously unknown X-ray sources with precise positions.
The Chandra Multiwavelength Plane (ChaMPlane) Survey is a project to
identify a large sample of these serendipitous X-ray sources in the
galactic plane, including cataclysmic variables, quiescent low mass
x-ray binaries, Be X-ray binaries and stellar coronal sources (see our
paper ``ChaMPlane: Measuring the Faint X-ray Binary and Stellar X-ray
Content of the Galaxy'' in this meeting). A pilot survey of this project
has been successfully conducted in clear weather at the CTIO 4m in
March, 2000 with the newly installed MOSAIC-II CCD detector. Nine
Chandra cycle-1 fields were observed. Photometry down to 24th R
magnitude in the galactic plane was performed in the V, R, I and
Hα bands. X-ray sources are identified by their Hα excess in
the R vs. (Hα - R) diagram. We will show the preliminary results
comparing with the available Chandra X-ray images, including the field
of the X-ray nova A0620-00 which has already been observed with Chandra.
