        UV_SELFCAL:  "Self"-Calibration of a UV data set

    UV_SELFCAL does a Phase and/or Amplitude Referencing of a  UV  Data set,
    using    another   one   representing   a   gaussian   source   observed
    quasi-simultaneously.  It is  STRONGLY  ADVISED  to  self-calibrate  the
    phase   first,  then  the  amplitude  using  a  longer  smoothing  time.
    UV_SELFCAL allows in addition to subtract (part of) the input  reference
    source, typically to provide continuum-free spectral line maps.
