8. What was measured?
... An OBJECT column gives the name of the object observed (usually a star name). ... 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. ...

... Proposal Type: General Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: ABSTRACT: Regular Pulsars Galactic 10 Hours 45 minutes A precise measurement of the mass of PSR J1950+2414 Millisecond pulsars are now known to have a much wider range of masses than assumed a few years ago (1.24-2.01 solar masses); there are indications that this range could be even wider. Therefore, when we attempt to measure the mass of a MSP, we never know what we will measure. ...
