Analysis export changes under Echoview 12

Improvements and changes for analysis export issues and outputs for new EV files created under Echoview 12 and on.

Behavior under Echoview 12

Previous issue

Fish track regions

Improvement of the handling of fish track regions that cross data files followed by the removal of a data file.

The end of the region uses the ping time to terminate as if the region extends on.

Such fish track regions clamped the end of the region to the last ping and terminated to a vertical point.

Density_weight, Density_number

When intervals are composed of all bad data or all excluded samples, and the Density_weight and Density_number can't be calculated, the output result is zero.

An incorrect value was exported.

ICES CSV

Analysis by Region Classes by Cells, To ICES CSV under a line-reference grid exports results as expected.

The export included duplicated rows with values set to zero.

Range_mean, Depth_mean

Analysis domains filled with no data output a value for Range_mean or Depth_mean.

Analysis domains with excluded samples (via exclusion lines) return zero for Range_mean and Depth_mean; this behavior is unchanged.

An incorrect value of zero was exported for analysis domains filled with no data.

Fish tracks by cells (database) export

Targets from invalid fish tracks are not list in the targets file.

Targets from invalid fish tracks were listed in the targets file.

3D_school_volume

3D_school_volume calculates as expected.

3D_school_volume was reporting zero in cases where it could be calculated.

Column changes for analysis export files

Changes for the following analysis exports under new EV files. Pre-existing EV files are unaffected by these new behaviors.
