Quality Assessment

All data have been compared with the current Harmonic Constants library, and residuals checked. Records have been visually inspected for spikes, datum shifts and timing errors.

Please Note: The Completeness index has been calculated for the primary channel only. Where there are multiple channels, the primary channel is ASLVBG02.

1200h 06 Sept 1976-1400h 07 Sept 1976 Gauge disconnected and temporarily reset to wrong datum.
