UV_DETECT Algorithm

          The UV_DETECT algorithm is basically that described by  Loomis  et
    al        2018        (2018AJ....155..182L,       see       https://arx-
    iv.org/pdf/1803.04987.pdf).  Here, instead of  being  implemented  as  a
    Python  /  CASA script, it is coded in Fortran and embedded into IMAGER.
    UV_DETECT calls an imager script that reads the  data  set,  computes  a
    UV_MODEL  from  the ImageData using the UV coverage found in the UV data
    set, resamples this UV_MODEL at the same velocity resolution than the UV
    data,  and  ultimately  calls command UV_CORRELATE to apply the UV plane
    filter.

      As described in the original paper, the UV data set and  source  model
    available  in  ImageModel  must  have the same centering. The ImageModel
    must also cover a sufficient width around its specified source velocity.

      The command will complain if the smoothing kernel described by the Im-
    ageModel is insufficient.
