Use the Data options to reject data with residual values that fall outside threshold limits, and apply these changes to attitude data across the entire track line, using the Filter and Smooth options.
The Filter function is used to reject attitude that falls outside of defined boundaries. Soundings with the same time stamp as the rejected data are also flagged as rejected during merge. You can choose to use interpolation when rejecting data.
The Smooth function is used to smooth out localized variability. Any sensor data that can be viewed in the Attitude Editor can be smoothed. The Smooth option activates all the options except Reject with interpolation.
