... 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....

In addition to time, frequency, and scale, there are two other coordinate axes within this transform space: shear-in-time (obtained through convolution with a q-chirp) and shear-in-frequency (obtained through multiplication by a q-chirp).
