我们在ASTE上安装了一个新的Band10接收器（790−940 GHz），并进行了调试和科学验证。我们用HCN脉射线(1110)-(0400)，J=10-9对IRC+10216进行了重复观测，确定了副反射镜位置和望远镜指向的筒体特定偏移量，然后获得了光束模式。根据光束模式估计光束尺寸为10.9″× 10.0″。为了科学验证，我们用CO （J=7-6）线对猎户座分子云1区猎户座- kl周围的8 ‘ × 4 ’区域进行了实时观测，验证了我们的图像与过去的结果一致，并证实了ASTE Band10观测到明亮和扩展物体的能力，如巨大分子云。
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.
