Data Range Bitmap
This operator creates a bitmap (Boolean or multibeam Boolean or color Boolean variable) with a true value for each input value that is within a specified range of values, and a false value for each input value that is outside the specified range. "No data" values are always translated to false.
Echoview accepts a single operand of the following data types as input:
- Angular position
- Color
- Complex angular position
- Complex power dB
- Complex Sv
- Complex TS
- Linear
- Multibeam angular position
- Multibeam color
- Multibeam magnitude
- Multibeam phase
- Multibeam Sv
- Multibeam TS
- Multibeam unspecified dB
- Power dB
- Pulse compressed complex angular position
- Pulse compressed complex power dB
- Pulse compressed complex Sv
- Pulse compressed complex TS
- Sv
- TS
- Unspecified dB

Description |
|
Minimum in-range data value |
Specify the minimum and maximum data values of the in-range for the bitmap. When the operand is a color variable, settings can be entered for the Red, Green and Blue components individually. When the operand is an angular position variable, settings can be entered for the Minor-axis and the Major-axis. Data values in the operand variable that are within the range are given a value of 'true'. Data values in the operand variable that are below the minimum data value and above the maximum data value will be given a bitmap value of 'false'. |

Notes:
- No data values in the operand variable will be translated to 'false' for the bitmap.
