SAOimage

SAOimage is the Xwindows (X11) image display program. It is relatively self explanatory, the best way to learn is by experiment. Here we provide a summary of available functions.

First bring up Xwindows by typing (if you are using sunview windows, exit sunview first; if you are a remote user, read SAOimage for Remote Users first:

  cfa#: startx

In any window, initiate iraf and load the xray package.

  cfa#: cd iraf
  cfa#: cl
  cl> xray

The task ximtool which initiates the SAOimage display is in the xplot package:

  xr> xplot
  xp> ximtool cfa#:0             # open window on your computer cfa#:.

A window will appear, which has several sections:

• the main image display (containing the SAO logo)
• the menu
• the text window (upper left)
• a full image display showing which portion of the image is shown in the main display window (upper middle)
• a magnifier window displaying a close up of the region around the mouse position (upper right)
• a large text window ( SAOmonolog) for status and verbose output

• SAOimage for remote users
• General usage.
• The SAOimage Menu (options within SAOimage)
• To produce a region mask using SAOimage interactively.
  • Select a circle around the central point source
  • A box, to include extended emission
  • A Region mask for a radial profile in concentric, elliptical annuli
• *fixsaoreg* --- restore SAOimage region to original image (physical) coordinates
