... The initial descriptions of the FITS format provided a simplified method for describing the physical coordinate values of the image pixels, but deliberately did not specify any of the detailed conventions required to convey the complexities of actual image projections. ... They were CRPIX n for the reference pixel location on pixel axis n , CRVAL n for the coordinate value at that pixel, CDELT n for the increment at that pixel in the coordinate value, and CTYPE n for the type of coordinate. ...

... 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....

... To track an object, the user specifies the object's position and also the desired orientation and position of the object on the instrument. The control system converts these to the position of the telescope and instrument rotator. Positions may be specified in several different coordinate systems, including FK4 (IAU pre-1985 RA/Dec), FK5 (IAU post-1985 RA/Dec) and apparent geocentric coordinates. ...

... Up: Description of program searchdup Previous: Program use . Input records are ordered per date of observation, and the list of known (observed) sources is cleared. Each record is compared in position to all the known sources. If the sky distance is less or equal to the specified one, the record is added to the list of observations for that source. If no known sources are within the specified radius, a new source is created, with the coordinates of the observation record. ...
