Such studies are important for understanding the evolution of cores to stars, and for comparison to formation processes in high- and low-mass star-forming regions. We used the SHARC II camera on the Caltech Submillimeter Observatory telescope to obtain 350um data having angular resolution of about 9", which corresponds to 0.02pc at the distance of Orion. Further data processing using a deconvolution routine enhances the resolution to about 3". Such high angular resolution allows a rare look into individually resolved dense structures in a massive star-forming region. Description: We have used the Submillimeter High Angular Resolution Camera (SHARC II), installed on the 10.4m telescope of the Caltech Submillimeter Observatory (CSO) to carry out the survey of quiescent Orion cores. During three observing runs from 2003 to 2005 at the CSO, we have obtained 350um maps for eight fields toward quiescent portions of Orion. File Summary:

Note (1): The source is identified by the survey region where the core is located followed by a sub number assigned according to its declination. Note (2): The sources are sorted from north to south.
