Change any of the values in the text fields and hit
to update the plot. The plot will automatically update after every change. The first column of parameters is to choose a form factor, P(q), the second column of parameters is to choose a structure factor, S(q). The only exception is the PolyHardSphere which has the structure factor included. In this case the choice of structure factor has no effect.
If you click in the plot area the following commands are available:
- r: redraw the plot
- R: redraw the plot and rescale it to the maximum range of the data
- c: bring up a small window that displays the current cursor position (Note: Some browsers do not correctly transfer the cursor focus back to the plot and away from the cursor position window. If this is the case you will need to click on the plot again for more commands to work.)
- d: draw a dot on the plot at the nearest data point to the mouse position and show the coordinates of the point in a small window. (Note: See note for c)
- D: close the data position window
- h: if pressed in the small windows brought up with c or d this will close that window
- m: brings up a dialog for setting the range of the plot manually
- drag mouse: click and drag on the plot to define a rectangular area to define new plot ranges. R will set the range back to the default.
Note: Some browsers will cause the applet to function improperly if you leave this page and come back to it. If you find that this is the case you can open this page in a new browser window and use the original one for browsing.
Note: We have also provided details of how the resolution smearing is performed.
