Notes page
The Notes page of the Variable Properties dialog box displays information about the variable.
General details
Some or all of the following details may be displayed:
Settings |
Description |
Variable name |
The unique name of the variable. You can change the name of raw variables and virtual variables with this setting. Echoview can assign a default name when a variable is created or when Reset is used.
|
Reset |
Resets the name to the name generated when data files are added or to the default name generated for a new virtual variable. |
Data type |
The data type of the variable |
Notes |
A text box in which you can enter extra information about this variable. Notes about the configuration of a bottom classification are added by Echoview when Classify Bottom is completed. |
Operator statistics
This section is available for some (not all) virtual variables, as follows:
Scan position
The operator statistics reported include:
- The number of possible frames identified.
These are the frames that will be detected if an instrument scanning school detection algorithm is applied to the variable which was specified as Operand 2. - For each frame identified:
- the ping numbers of the first ping and last ping of the frame
- the mean distance each ping (in a frame) is moved by this operator
- the standard deviation of the distance each ping (in a frame) is moved by this operator
- The number of possible target-locked ping pairs identified.
These are the target-locked pings that will be detected if the target-locked school detection algorithm is applied to the variable which was specified as Operand 2. - For all target-locked ping pairs calculate:
-
- the mean distance each ping (of all target-locked ping pair sets) is moved by this operator;
- the standard deviation of the distance each ping (of all target-locked ping pair sets) is moved by this operator
- For each set of target-locked ping pairs identified:
- the ping numbers in both Operand 2 and the Target-locked variable specified on the Data page of the Variable Properties dialog box for Operand 2 in the following format:
pings (first) - (last) are locked (x)
where:(first) identifies the first target-locked ping pair in the set in the format (a, b) (last) identifies the last target-locked ping pair in the set in the format (a, b) (a,b) identifies a target-locked ping pair, with
a being the number of the ping in Operand 2 and
b the number of the ping in the Target-locked variable.(x) is either simultaneous or alternate to indicate the way in which the pings were locked. See Target-locked scanning. and all of the ping pairs between (first) and (last) were identified as target locked.
- the ping numbers in both Operand 2 and the Target-locked variable specified on the Data page of the Variable Properties dialog box for Operand 2 in the following format:
