254. Change a profile parameter
26</H1>
[207]27The next step in the tutorial is to change a profile parameter,
[160]28in this case to widen the range of peaks that are fit. This is done
[207]29by switching to the Profile pane and
30selecting each histogram by selecting it in the box
[160]31to the left. Then change the "Peak cutoff" from 0.01 (1%) to 0.005
[207]32(0.5%). Note that this change can slow down GSAS significantly, but
[160]33is useful when the the signal-to-noise ratio is very good.

36After the first histogram is modified, select the second histogram
37and modify the "Peak cutoff" there as well.
