It is not necessary to eliminate overlap or order the ranges in any sense. The resulting RMS of the data with respect to the fit is displayed in the window. You can choose to have the baseline recalculated each time or you can choose to simply use the most recently calculated baseline. You can also choose to have the baseline removed from the data or simply displayed over the data. The height of each range box on the plotter indicates the local RMS of the data and the center Y value of each range box indicates the local mean of the data.
Channels are channel numbers.
This button doesn't actually change any values, it just changes what the baseline fitter thinks the units are for those values. This conversion is always done using whatever record was most recently displayed on the plotter. The goal here is to allow the user to migrate away from the GUI for batch operations and routine processing by showing them what the program is doing. All of the variables shown in the results manager are available at the glish prompt for the user to use. At this point, however, the glish code displayed in the trace window is not what the program is actually doing, although we think it is representative of what the it will eventually be doing.
