    99=== Step 1: Clear calibration plot   ===

    11 Assuming the previous step was calibration, the image plot will show the located rings or the picked points. These are no longer needed. The Image Controls/Clear Calibration menu entry removes these intermediate results, ''but does not clear the calibration results''. Use of this menu item is not required, but does speed future display of results.

    15 In the simplest case, all that is needed is to click on the "Do full integration?" checkbox and likely adjust the inner and outer 2-theta values with the two "Inner/Outer 2-theta" controls. For the La_hex_+45deg-00015.tif image loaded before, good values are 0.5 and 7 degrees.

    1717It is helpful to see the two-theta limits on the plot visually, while adjusting the two-theta range. This is done by clicking on the "Show integration limits?" checkbox. Note that inner limit is shown as a green ellipse and the outer is shown as a red ellipse ([https://subversion.xor.aps.anl.gov/trac/pyGSAS/attachment/wiki/DemoIntegrateTilted/d2w1.jpg view]).

    31  Use the Image Operations/Integrate image data menu item to start the integration. This will take at least a few seconds. If multiple images have been read in, the Integrate All menu item can be used. This is most useful when the "Use as Default" option is in use for one image.
