Pressing a smoothing key will smooth the data with the corresponding
width. A width of 25 points means that features which span less than 25
bins will be smoothed out. The time displayed in each menu box is the
smoothing width multiplied by the bin width and represents the real time
smoothing width.
All of the data record in the display memory is smoothed, regardless of
the graph display. While calculations are in progress, the "Calculating"
message is displayed below the graph. Smoothing may be repeated until
the desired noise reduction is attained.

when the Smooth menu is exited. If floating point data is saved to disk
using the Save Trace function, it will be recalled as floating point data us-
ing Recall Trace. To avoid accidentally losing original data, save the
count data to a disk file before performing Smooth menu opera-
tions.
