About ECS files

ECS files are a powerful calibration tool that allows you to set/modify calibration settings for Calibration Sources used by raw acoustic variables and virtual variables. ECS is an abbreviation for Echoview Calibration Supplement file (*.ecs); its plain-text format allows you to specify calibration settings that:

  1. Can seamlessly apply settings to all variables in a fileset by using Fileset section of the ECS file.
  2. Can seamlessly modify a variable's Calibration Source by using SourceCal section of the ECS file.
  3. Can apply settings to selected variables by using LocalCal section of the ECS file.

The ECS file, introduced in Echoview 5.0, is a key component of the Echoview calibration model to facilitate calibrated data for quantitative analysis. Different Echoview calculations may require different calibration settings, so we recommend you regularly assess the suitability of the settings used on the Calibration page for each acoustic raw variable or the Calibration page for each acoustic virtual variable. The Message dialog box will display messages about the use of default values.

Modifications to calibration settings are handled by an ECS file that is added to a fileset. An EV file template copies an added ECS file path and name. As a result one ECS file could be used with many EV files that handle related data from a survey. One consequence of this convenience, together with the override nature of settings applied by an ECS file, is that an ECS file may affect multiple EV files or multiple variables. For more information refer to Echoview Calibration Supplement files.
