Time Series Range Bitmap

This operator creates a bitmap using the ping geometry of operand 1. Every data point in each output ping will be true if the time series value (from operand 2) at the time of that ping was within the specified limits, and false otherwise.

Description

Minimum in-range value

Specify the minimum and maximum values for the time series range check.

For each ping, data values in the operand variable are evaluated against the specified range (inclusive). If the time series value at a given sample is within range, that sample is assigned a Boolean value of 'true', and otherwise 'false'.

Maximum in-range value

Note: You can edit the Minimum and Maximum limits in any order. The operator validates the range when it runs. If the range is invalid, a warning is raised and a message is displayed in the echogram. Adjust either bound to continue.
