Large Scale Mapping of the $\rho$ Ophiuchi Regions by SWAS

We have completed a 3 square degree CI ${}^3$P${}_1$-${}^3$P${}_0$ map of the \r
Ophiuchi regions using SWAS. The remarkably stable receiver and backends systems of SWAS allow for uniformly calibrated data set on this scale. Combined with \co, \13co, and \c18o maps made using FCRAO, this data set will facilitate a thorough study of the physics and the chemistry in this nearby star forming region.
