Averaged spectrum of the CS (5–4) line at 244.936 GHz toward comet C/2001 Q4 (NEAT) observed on UT 11.03 May 2004 with the AOSA (thick blue line), AOSB (thin red line), and CTSB (black line). The vertical axis is the calibrated main beam brightness temperature and the horizontal axis is the Doppler velocity in the comet rest frame. The rms noise level measured with respect to the zero reference level is shown by the blue, red, and gray bars close to the origin of the figure for AOSA, AOSB, and CTSB, respectively.
