Projection Plot

To overlay Projection plots (simultaneously viewing multiple projection plot overlays with similar range on the same plot)

  1. Select column to be plotted on the RA-axis.
  2. Select column to be plotted on the Dec-axis.
  3. Click on the plot button.
  4. Select column to be plotted on RA-axis for the overlay.
  5. Select column to be plotted on DEC-axis for the overlay.
  6. Select the Overlay option.
  7. Click on the plot button.

A different color will be used for each overlay, to allow one to differentiate between the overlays. A default legend showing the meaning of each overlay is shown on top-left side of the plot. This can be modified from inside the Plot Properties --> Advanced tab.

Example of overlaid Projection Plots is shown in the Figure below:
