Abstract

We installed a new Band10 receiver cartridge (790 − 940 GHz) on ASTE and carried out its Commissioning and Science Verification. We repeated observations toward IRC+10216 with HCN maser line (1110)-(0400), J=10-9, determined the cartridge-specific offsets of sub-reflector position and telescope pointing, and then, obtained beam patterns. The beam size was estimated to be 10.9″ × 10.0″ from the beam patterns. For science verification, we performed observations of an 8′ × 4′ area around Orion-KL of the Orion Molecular Cloud 1 region with CO (J=7-6) line in the on-the-fly method, verified that our images were consistent with past results, and confirmed the capability of ASTE Band10 observations toward bright and extended objects like Giant Molecular Clouds.
