UV_REF_MODEL does a Phase and/or Amplitude self-calibration of a UV
table, another observed UV table for which a correct model is known. In
- UV_REF_MODEL self-calibrates first the observed visibilities of the
modeled source used as reference. The self-calibration is baseline
based (i.e. it does not take into account closure relationships).
- UV_REF_MODEL then applies the gains derived in previous
self-calibration to the visibilities of the source to be calibrated.
It is STRONGLY ADVISED to self-calibrate the phase first, then the am-
plitude using a longer smoothing time. Moreover UV_REF_MODEL enables to
subtract (part of) the input reference source, typically to provide con-
tinuum-free spectral line maps.
See also UV_REF_POINT, UV_REF_GAUSS, which does the same thing, but us-
ing a point and a Gaussian source as input.
