 === Step 1: Clear calibration plot   === 
 
- 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.

 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. 
 
-It 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. Note that changes are displayed only after pressing return, when numbers are placed in the boxes.

 Other useful controls:

- Number 2-theta bins:
- Number azimuth bins:
+ Azimuth offset: The image vertical axis (from the beam center, going upwards) is labeled with the azimuth value placed in the "Azimuth offset" box. This is usually zero.
+
+ Start/End azimuth: The integration is started at the Start azimuth angle in the left box, and when the "Do full integration?" checkbox is not checked, then the integration will be run only to the maximum value specified. When the range is less than 360 degrees, the integration range will be shown (if selected) with the high and low limits plotted and only segments of the max and min ellipses drawn.

+ Number 2-theta bins: The resulting 1-D powder pattern after integration will consist of this many points. This number should be on the order of the number of pixels in one direction (since resolution cannot be much better than this) or less, if instrumental resolution does not require that many points.
