Description:
    We have made a complete survey of the CS(2-1) emission toward IRAS
    point sources in the galactic plane. The sources observed were
    selected according to their far infrared (FIR) colors, which are
    characteristic of UC HII regions. They have 25{mu}m/12{mu}m flux
    ratios larger than 3.7 and 60{mu}m/12{mu}m flux ratios larger than
    19.3. The survey covered a region from b=-2deg to b=2deg from l=300deg
    to l=0deg and from l=0deg to l=60deg, and from b=-4deg to b=4deg
    elsewhere. We detected 843 sources out of 1427 sources observed. The
    distributions of detected and undetected sources in a FIR color-color
    diagram show some differences, suggesting that more than one type of
    object is present in our observed sample.
