The following are specific recommendations for processing raw measurements, which are non-specific to a brand/make of instrument. As such, initial removal of bad data based on recommendations of the instrument manufacturer should be performed first (e.g. removing data with low correlation). Following that, you must:
- Despike the velocity observations
- Identify whether there is interference from the instrument frame, and under which conditions
- Determine the measurement noise levels in the time-domain This is currently not implemented, would be best done on each segments at level 2
