In general, command
SHOW allows a per-plane display of any SIC
3-D image variable, with contours overlaid on bitmap for each plane:
e.g.
SHOW DIRTY 30 -30
will display contour and bitmaps of each channel of the DIRTY
image, starting for channel 30 and ending 30 channels before the last one.
See Fig.
for an example.
A direct use on Gildas 3-D image or UV data files is also possible: SHOW Filename.ext will directly display the file if possible. It also works for simple FITS files in which the data array is in the HDU.
For uv data,
SHOW UV can plot visibility values
such as amplitude as a function of time, baseline length, etc...,
again on a per channel basis. Fit results can be overlaid, as
shown Fig.
SHOW can also display more specific issues:
