Target Acquisition Reference Information . Chapter 4 mentions acquisition methodologies for extended objects, and, in particular, the use of the EXTENDED Optional Parameter. In this section we provide some guidance on predicting the count rates to be expected during an acquisition of an extended object, especially one beyond our own Galaxy. The renewed availability of Side 1 of the GHRS and its G140L grating make it possible to get high-quality spectra of faint objects efficiently. ...
