In critical cases, it is common practice to measure sky on two or more positions around a target object, and these positions must be identified. ... A general treatment of this problem requires a column called OBJECT, bearing the usual name of the object (as in the star tables); a column labelled STARSKY, to distinguish between star+sky, star alone, or sky alone; and additional columns to identify the sky position. ...

... According to theoretical calculations, this effect can be measured by observing PSR B1937+21 for four hours. The measured magnitude and frequency dependence of the HI resonance delay will complement measurements of the HI optical depth thus giving us more information about HI clouds in the ISM than can be obtained from optical depth measurements alone. Students involved in the Arecibo Remote Command Center at UT Brownsville will be involved in the observations and data analysis. ...
