Depth

Set minimum and/or maximum depth values to filter out soundings above and below the specified values.

Enable

From the drop down list:

• Select Both to apply min/max filtering.

• Select Minimum to filter only shallow values.

• Select Maximum to filter only deep values.

Default is None.

Minimum

Type a value above which shallower soundings will be filtered out.

Maximum

Type a value above which deeper soundings will be filtered out.

Beam Numbers

Filter single or multiple numbered beams.

Enable

Set check box to False to skip beam number filtering. Default is set to True.

Values

Enter the numbers of the beams to be rejected.

• Separate individual beam numbers with a space e.g., values 12 32 46 will reject beams 12, 32 and 46.

• Specify a range of beams with a hyphen e.g.,56-60 will reject beams 56, 57, 58, 59, and 60.

Beam to Beam Slopes

Slopes before and after a beam value across track are used to filter outliers.

Enable

Set check box to False to skip outlier detection. Default is set to True.

Across Track Angle

For each beam on the same swath, calculate the slopes in degrees to the prior and post beams. If both slopes exceed the defined value and are of opposite sign, then filter the beam.

Default value is 20 degrees.

Include rejected

This option includes previously rejected soundings when recalculating the slopes during multiple runs of the filter.

Status

Select a status flag to specify whether data is accepted or rejected by the filter process.
