[26.01] SHARC II Observations of the Galactic Center

We present the first images of the Galactic Center region obtained with the new Caltech Submillimeter Observatory facility camera SHARC II. Most of the observations show the 350\mum dust continuum emission from this region. The observing mode we used is similar to fast scanning. This mode does not require on- and off-source observations, since the emission from the sky and detector noise can be derived from the on source observations alone. This is possible because the fast scanning on the sky provides spatial correlations between bolometer pixels due to atmospheric emission and temporal correlations between pixels due to celestial emission. This difference of correlations permits the separation of the atmosphere from the celestial source. The observations therefore do not suffer from possible contamination from emission in an off position used for sky subtraction.
