UV_ASCAL

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

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