Display

ORAC-DR optionally lets you inspect the raw frames, and the processed data as they are created. There is a variety of graphical methods available, including histograms and contour plots, if you choose a KAPPA GWM widget. Most people prefer a simple scaled image display with GAIA. This offers facilities to inspect and analyse the data, and both pixel and sky co-ordinates of the cursor position are presented. The selection of frame types to display, where they should appear, and how they are scaled are configurable using a simple text file or a special GUI tool oracdisp. See SUN/230 for details and examples.

Processing offline, there is less need to see the data displayed in real time. If you wish to accelerate the processing switch off the display option.

If you do want to display a recommendation is to create two GAIA windows displaying images using autoscaled limits. This first could be for raw and flat-fielded data, and the second for the mosaics. You are likely to want to interact with the latter, using GAIA's toolboxes. Your $ORAC_DATA_OUT/disp.dat could look like this.

      # Send raw frame to first GAIA window 
      num type=image tool=gaia region=0 window=0 autoscale=1 zautoscale=1

      # Send flatfielded frame to first GAIA window.
      ff  type=image tool=gaia region=0 window=0 autoscale=1 zautoscale=1

      # Send mosaic frame to second GAIA window.
      mos type=image tool=gaia region=0 window=1 autoscale=1 zautoscale=1
