Notes. Data are merged from A-configuration and D-configuration. Quoted errors include the rms errors of the Gaussian fits in the uv plane and the absolute flux calibration accuracy of 20%. The SO2 line parameters are retrieved from the CDMS and are based on the calculations by Lovas (1985) and Müller & Brünken (2005).
