Velocity and Filter Look-Up Tables

The Eureka2R uses the values in the table below as default values based on

be adjusted as described in this manual. The abbreviations representing the
individual materials are used by Eureka. When using an Accelerometer -
Hydrophone sensor combination, select the default filter settings for
Hydrophone - Hydrophone.
