Calibration of an area detector in GSAS-II

In this demo, data collected with a GE(?) area detector, intentionally tilted at 45 degrees, are used

Step 1: download the data file from one of these links

​https://subversion.xor.aps.anl.gov/trac/pyGSAS/browser/Examples/images/tilt-11ID/La_hex_%2B45deg-00015.tif?format=raw or ​https://subversion.xor.aps.anl.gov/pyGSAS/Examples/images/tilt-11ID/La_hex_+45deg-00015.tif

Step 2: start GSAS-II in the directory where you have placed that file. This is done in different ways depending on your OS and how GSAS-II is installed.

Available python module versions for GSASII:

You should see two windows, both empty. One is labeled GSASII Plots, the other GSAS-II data tree. On Linux and Windows a menu bar appears on the latter window; on a Mac the menu is in the system location (usually at the screen top).

Step 3: read in the data file.

Use the Data/Read? image data menu item . Select the La_hex_+45deg-00015.tif data file and press Open.

At this point the data tree window will have several entries
