12. Click OK . The script will return with a graph showing the response of the
sensor in terms of amplitude and phase plots for each component (if
appropriate.)
13. The accuracy of the results depends on the amount of data you have selected,
and its sample rate. To obtain good-quality results at low frequency, it will save
computation time to use data collected at a lower sample rate; although the
same information is present in higher-rate streams, they also include a large
amount of high-frequency data which may not be relevant to your purposes.
14. The bbnoisecal script automatically performs appropriate averaging to
reduce the effects of aliasing and cultural noise.
