We present a Galactic plane survey in the J=1-0 transition of 13CO using the 7-m telescope (beamsize of 100'') at Bell Laboratories. The range of survey is (l, b) = (5\circ ~117\circ, -1\circ ~+1\circ), comprising about 224 square degrees. A total of ~ 56,000 spectra has been obtained with a grid spacing of 3' for |b| < 0\circ.5 region, and 6' for |b| > 0\circ.5 during hundreds of days of observing over the ten-year period. The entire mapped region was resampled into 3'-grid. The velocity range is -127 to 147 km s-1 with a 0.68 km s-1 resolution. The raw data (in COMB form) were transformed into FITS format, and all the reduction processes, such as cleaning, baselining and interpolation were conducted within IRAF using fcrao task package and several programs of our own. The rms noise level of the survey is ~ 0.1 K in 0.68 km s-1 channels. In this poster, we present first results of 13CO Galactic plane survey, including integrated intensity, spatial-velocity maps, and statistical analyses.
