NAME

gpboot - Correct the gains table of a visibility data-set.

DESCRIPTION

GpBoot is a MIRIAD program which corrects a visibility data-set's gain table.

GpBoot works by comparing the amplitudes in the gain table of one data-set with those of another. The gains are assumed to differ by a constant factor. It is assumed that the instrumental gain and atmospheric attenuation of the two data-sets were the same, and so the difference in gain is due to an arbitrary or incorrect flux being specified when initially determining the gains.  

PARAMETERS

vis
The input visibility file, containing the gain file to correct. The gains are assumed to be out by a constant factor.
cal
This is a visibility data-set, which is assumed to contain a gain table which scales the data to absolute flux units.
select
Normal uv-selection parameter. This selects the gains in the ``vis'' that are compared against the ``cal'' gains (note that all the ``cal'' gains are involved in the comparison). Currently ONLY time and antenna selection are permitted. You will use this parameter to select which data the instrumental/atmospheric amplitude gains for ``vis'' are comparable to the observation in ``cal''.
