Title: ChaMPlane Survey: Spectroscopy and Calibration Follow-up

Abstract: We propose to continue our Chandra Multiwavelength Plane (ChaMPlane) Survey spectroscopy and calibration follow-ups using the CTIO telescopes. The ChaMPlane Survey is a project to identify a large sample of serendipitous X-ray sources located in deep galactic plane fields imaged by the Chandra X-ray Observatory. These sources include cataclysmic variables (CVs), quiescent low mass X-ray binaries (qLMXBs), Be X-ray binaries and stellar coronal sources\citegri02b,gri05. We have just completed our 5-year ChaMPlane imaging survey, which is one of the NOAO Long Term Survey Programs, and produced 65 Mosaic fields covering about 23 square degrees and 154 ACIS observations on 105 distinct Chandra fields. The spectroscopy follow-up for ChaMPlane object classification is the final, crucial step for completing the survey. The photometric calibration is critical for establishing the NOAO survey database which we are committed with, in order to provide the community with all our optical images and the star magnitudes. This year we have successfully conducted a CTIO-4m/Hydra spectroscopy run. Here we propose to continue our follow-up spectroscopic and calibration programs in the year 2006.
