Description:

We have obtained chopped near-infrared maps at 1.25, 1.65 and 2.2 micron in the Serpens dark cloud (S68) centered on IRS3. They show unresolved structure, most likely due to illumination of scattering grains, out to 1´ from the center. The combination of high reddening (and 3.07 m absorption) and asymmetrical optical reflection points to a non-spherical dust distribution typical for bi-polar flow sources. In addition to the maps at 3,H,K, which consist of 19 by 47 pixells spaced by 2, we are using (Gunn r. and z) CCD images taken at Palomar by Bel Campbell. We are developing software to process these and similar intrared maps using a modified maximum entropy technique. The modifications have been necessary, to avoid singularities inherent in the standard maximum entropy algorithm when it is applied to data with zerovolume point-spread functions.
