... 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. ...

... The user provides SCHED with source coordinates in one of the J2000, B1950, or DATE coordinate systems. ... This date is specified using PRECDATE . ... This is enough to harm phasing of the VLA at high frequencies and enough to be rather undesirable for positions used on the correlator. ... For example, the B1950 coordinates of the VLA calibrators are either based on absolute measurements made in 1979.9, or are converted from more modern J2000 coordinates using an assumed ``observe'' date of 1979.9....

... The main purpose of this task is the correction for attitude drifts using the dispersion coordinate system. The dispersion coordinates are defined based on the position and on the orientation of the RGA, and have two components: the dispersion angle BETA and the cross dispersion angle XDSP . ... This is called reference attitude and basically means that this is the on-axis sky position to which the telescope points after the attitude drift correction was performed. ...
