Beginning of ReadMe : J/ApJ/671/470 MIPS survey of YSOs in Vela Molecular Ridge-D (Giannini+, 2007) ================================================================================ Spitzer MIPS survey of the young stellar content in the Vela Molecular Ridge-D. Giannini T., Lorenzetti D., De Luca M., Nisini B., Marengo M., Allen L., Smith H.A., Fazio G., Massi F., Elia D., Strafella F. <Astrophys. J., 671, 470-482 (2007)> =2007ApJ...671..470G ================================================================================ ADC_Keywords: Surveys ; Molecular clouds ; Infrared sources Mission_Name: Spitzer Keywords: infrared: stars - ISM: clouds - ISM: individual (Vela Molecular Ridge) - ISM: jets and outflows - stars: formation - surveys Abstract: A new, unbiased Spitzer MIPS imaging survey ( 1.8deg^2^) of the young stellar content of the Vela Molecular Ridge-D (VMR-D) is presented. The survey is complete down to 5 and 250mJy at 24 and 70mum, respectively. A total of 849 sources are detected at 24mum, and 52 of them also have a 70mum counterpart. The VMR-D region is one that we have already partially mapped in dust and gas millimeter emission, and we discuss the correlation between the Spitzer compact sources and the millimeter contours. About half of the 24mum sources are located inside the region delimited by the ^12^CO(1-0) contours, corresponding to only one-third of the full area mapped with MIPS. Therefore, the 24mum source density increases by about 100% moving from outside to inside the CO contours. For the 70mum sources, the corresponding density increase is a factor of 4. About 400 sources of these have a 2MASS counterpart, and we have used this to construct a Ks versus Ks-[24] diagram and to identify the protostellar population inside the cloud. Description: The VMR-D cloud was observed with MIPS on board the Spitzer Space Telescope within the Guaranteed Time Observation program (PID 30335). The observations covered 1.15deg (in right ascension) x 1.6deg (in declination) centered at RA,DE=8:47:50, -43:42:13 (J2000.0) and 8:48:20, -43:31:26 (J2000.0) at 24 and 70mum, respectively (orientation: 145deg west of north). Data were collected on 2006 June 14.
