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.
