Single-Sideband Calibration for CO, 13CO, HCN, and CS Lines near 345 GHz
Abstract
We present calibrated single-sideband spectra toward nine standard sources in CO J = 3 - 2, (13)CO J = 3 - 2, HCN J = 4 - 3, and CS J = 7 - 6 lines. These spectra were taken at the Caltech Submillimeter Observatory (CSO) 10.4 m telescope using a solid-state imaging spectrometer (SIS) receiver and a quasi-optical single-sideband filter. The image rejection of the single-sideband filter was 11 - 13 dB near 345 GHz. The spectra presented are meant to serve as standard calibrators for these lines.
