The Spitzer c2d survey of large, nearby, interstellar clouds.: VII.: Ophiuchus observed with MIPS

We present maps of 14.4 deg(2) of the Ophiuchus dark clouds observed by the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer ( MIPS). These high-quality maps depict both numerous point sources and extended dust emission within the star-forming and non-star-forming portions of these clouds. Using PSF-fitting photometry, we detect 5779 sources at 24 mu m and 81 sources at 70 mu m at the 10 sigma level of significance. Three hundred twenty-three candidate young stellar objects ( YSOs) were identified according to their positions on the MIPS/2MASS K versus K - [24] color-magnitude diagrams, as compared to 24 mu m detections in the SWIRE extragalactic survey. We find that more than half of the YSO candidates, and almost all those with protostellar Class I spectral energy distributions, are confined to the known cluster and aggregates.
