Notes. (a)Given at the frequency of 180 GHz, 196 GHz, 230 GHz, and 345 GHz for SEPIA180, PI230 (4–8 GHz IF), PI230 (4–12 GHz IF), and FLASH345, respectively. (b)Given for a resolution of 0.7 km s−1on TMB scale. All frequencies were covered twice, except for the one at the edges of the bands, corresponding to the frequencies 159–161 GHz, 186–188 GHz, 318–320 GHz, 328–330 GHz, and 372–374 GHz, where the rms is higher by a factor 
.(c) Excluding sidebands covering telluric water lines.
