Abstract
Three rotational transitions of the CS molecule were observed toward the negative longitude half of the molecular disk which orbits about the galactic center between radii of 2 and 10 pc. A comparison of the relative line strengths allows a determination of the radial run of density in the circumnuclear disk. In order to observe all of the transitions with a similar beamsize, the two lower frequency transitions were measured with the IRAM 30-m telescope, and the highest frequency transition with the NRAO 12-m. Table I lists the observing parameters.
