This panel is brought up by selecting a lattice in the "Show Powder Diffraction Lines" drop-down box in the
Plot window. You should already have made a radial plot of some sort (plotting versus Q, 2-theta, or Q2).
At the top of the window is some basic information and a simple schematic relating to the lattice selected.
Below this are text windows and sliders for the parameters that can be varied for this lattice. This will include some or all of
the lattice parameters, a, b, and c, and the lattice angles alpha, beta, and gamma. In general, only some of
these parameters can be varied. For example, in a rhombohedral lattice, b=a, so b cannot be varied, and there is one
lattice angle gamma that can be varied.
Click "Apply" to show the indexed diffraction line positions on your plot. Type into the boxes or drag the sliders to change the variables. Click "Reset Limits" to reset the range of the sliders from the plots--Datasqueeze does its best to guess a reasonable range for each parameter given the limits of the plot and the symmetry of the lattice. Click "Clear" to remove the diffraction lines from the plot. Click "Change Limits" to pull up yet another windows for manually setting the range of each slider. Note that if the "Show Powder Rings" check box has been set in the Image panel then rings for the region of interest will also appear on the false color image. |
