Warning
Long forgotten GILDAS Tips & Tricks. This should probably be extended. Using more examples, in particular for clic and mapping

Gildas/Clic

  • Change the bandpass calibrator :
let band_source "sourcename" after clicking on select
180 degree Jumpy Phase :
set phase degree jumpy
PLOT /IDENTIFY col
SOLVE phase /PLOT
  • Change the number of time interval for spline interpolation :
SET STEP 4 (in hours, default 3)
  • Make polynomial phase fit instead of spline :
SOLVE phase /PLOT /POLYNOMIAL 6
  • Remove the last drawn plot layer :
CLEAR seg
Plot the closure relations :
PLOT closure
  • Change the averaging in time when plotting :
SET AVERAGING none
SET AVERAGING TIME 5 (seconds)
  • Change the reference antenna for RF and phase calibration :
SET REFERENCE x (logical number)
  • See the correspondance physical/logical antenna :
SET ANTENNA ALL

Gildas/Mapping

  • Reproject one image to another :
run reproject
