After the drift has been removed, the frequency residuals can be seen in the small plot on the status bar. Notice that the filename extension has been incremented to indicate that the data has changed., and that the unsaved icon has appeared. In addition, the icon indicating that the phase and frequency data are equivalent has gone away. You can also see the date, data type, # of data points, tau, and the analysis start & end values. Changing the latter, or clicking on the plot, will change the portion of the data that is plotted, and another indicator will be show that the data is zoomed. We can see that the drift-removed frequency data is essentially white.
