Appendix 1: System parameters
The web user interface presents the raw and processed parameters to the user through
the Dashboard page. Tables 1 to 6, describe all the parameters that are measured and
calculated by the WaveGuide Onboard 2 system. Unless stated otherwise, all processed
parameters are calculated once per minute and are based on the most recent 20 minutes of
data.
