Calibration Subset

This operator outputs a variable containing the subset of pings whose specified calibration setting is within a range of values.

Enter the processing settings for this operator on the Calibration subset page of the Variable Properties dialog box.

The Calibration Subset Variable Properties dialog box pages include (common) Variable Properties pages and these operator pages:

Operands page

Calibration Subset page

The Calibration Subset page specifies a Calibration setting, the specified values for the calibration setting and the pings to be included for the output Calibration subset virtual variable. Press Apply or OK to update the Calibration subset variable.



Calibration setting

A calibration setting selected from the Calibration setting list. Descriptions of settings may be found on these pages: Common calibration names and Calibration names specific to transducers.

Ranges of calibration values in the operand

The range of values for the selected Calibration setting. The ranges are entered as Minimum value:Maximum value. When no Maximum value is supplied, the range extends to infinity. Multiple ranges may be separated by commas.

Include pings within the ranges

Exclude pings within the ranges

Select to include or exclude the pings that satisfy the calibration value range.
