... The Miriad task uvgen can be used to simulate a variety of observing modes. ... Simulating a telescope approximately, let alone in some detail, requires a good many parameters. uvgen takes an appreciable number of parameters and input files to describe the telescope, correlator and source.

... The G_ERR column is an unsigned short int (16-bits). By some FITS convention, 16-bit unsigned numbers are stored with an offset of -32768. So, you need to add 32768 to G_ERR to get the right value. If you look at the file with " fv ", fv adds the correct offset form the file header. So, when there is no error condition G_ERR should have a value of 0 (-32768 stored in the file). ... errors in previous 1s . ... wideband up shift saturation . ... narrowband up shift saturation . ...
