... User Guide ] Task: uvsfit Purpose: Fit point sources to a given vis file. ... You can reduce the data volume by averaging in frequency using the line parameter (apply bandpass first) or selecting a subset of the data. If you want to produce model or residual visibilities at full resolution for all the data, you can run UVSFIT again with all source parameters specified and fixed. ...

... If you have centered the object on the chip the pattern will put the object in each of the 4 quadrants of the chip. ... They are the offset in arcseconds for the x and y inst plane offset, the exposure time in seconds, and the number of exposures at each position. ... A point about offsets should be made here. The dither program uses absolute instrument plane offsets, so you should use object plane offsets to center up on the chip so that the script starts from where you centered up. ...
