... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...

... The caption to Color Figure 3 refers to the source 1928+734, which should be 1928+738. In the summary section on page 49 (Murphy et al.), the sentence "In that time, we have observed a variety of structural changes in the inner jet region near the region." should read "In that time, we have observed a variety of structural changes in the inner jet region near the core."

An AAS Electronic Announcement Dear Colleague: NASA has approved development of a Wide Field Camera 3 (WFC3) for installation in the HST on the 2002 Servicing Mission. A Scientific Oversight Committee (SOC) is being established to ensure that the broad interests of the scientific community are represented in the development of WFC3. The primary task of the SOC will be to advise the HST Project and STScI in all areas of scientific performance of WFC3. ...

... In the spectrometry of point sources, the advantage of obtaining long slit spectra over using single aperture spectra is that it provides a simultaneous spectrum of the background on both sides of the point source. ... The STECF IRAF layered package "specres" provides two tasks to extract point source spectra from 2-D images (either longslit, multislit or cross-dispersed) and decompose the full background over the image. ... A Point Source Function spectrum image is required as a 2-D spectrum. ...
