An AST/RO Survey of CO(4-3) in ultracompact HII regions
Abstract
Description
The Antarctic Submillimeter Telescope and Remote Observatory (AST/RO) has been used to observe 78 of the IRAS point sources identified by Bronfman et al. (1996) as likely ultracompact HII regions. Results for the CO(4-3) line at 461.041GHz are presented. The 74 sources detected are bright and in many cases compact, making them potentially suitable as pointing calibrators for single dish submillimeter telescopes.
