CMG-CD24

The accuracy of the results depends on the amount of data you

have selected, and the 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.

The calibration script automatically performs appropriate
averaging to reduce the effects of aliasing and cultural noise.
