[4.23] Star Counts in the NOAO Deep Wide-Field Survey

The NOAO Deep Wide-Field Survey will survey two ~9 sq. deg. regions of sky in a suite of optical (Bw, R, I) and infrared (J, H, K) bands. Although designed primarily to study the formation and large scale structure of galaxies, the survey can also be used to identify rare stellar populations in the Galaxy and to study Galactic structure. Here we compare the Bw, R, and I star counts in a small portion of the Cetus field of the NOAO Deep Wide-Field Survey with the counts predicted by a simple Galactic structure model. The comparison is used to explore the accuracy of catalog-generation programs such as Source Extractor in performing star-galaxy separation at faint magnitudes.

The NOAO Deep Wide-Field Survey is being supported by the National Optical Astronomy Observatory which is operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the National Science Foundation. Michael Cooper's research was supported by the NOAO/KPNO REU Program, funded by the National Science Foundation.
