This survey in the (J = 1 → 0) line of CO at 115 GHz was conducted in 1993 and 1994 using the 1.2m millimeter-wave telescope at the CfA (see Oliver et al. 1996 for more complete description). The survey area, l = 196.0° to l = 206.5°, b = −1.5° to b = +3.5° was covered on a square grid in l and b with spacings of 3′.75 (0.4 FWHM) to give uniform sensitivity. All the spectra were position switched against positions measured be free of CO to 0.05 K. Each spectrum has 256 channels 0.25 MHz wide, giving a resolution of 0.65 km s−1 over 166 km s−1. The channel to channel noise temperature in the original spectra was 0.24 K (RMS) which was reduced to 0.115 K per beam by smoothing to 10′.
