Spectrum Statistics

At some point during your data reduction you might want to know a little more about your spectrum. There are several commands which determine the parameters of spectra. Two of the more useful commands are find-spectrum-statistics and find-integrated-intensity. There are others in R. Padman's manual.

To use these commands in interactive mode you get a plot of the current spectrum like you did when removing and fitting baselines so that you can specify a region. Just use the cursor or crosshairs and l, r, and a as you did before.

Once again it may be useful to write the outputs to a separate file using the s-l-f command.
