Progress Report NORSAR Phase 3

Abstract

The report covers operation and research activities at the Norwegian Seismic Array (NORSAR) in the period 1 October - 31 December 1974. A small increase in the number of instruments with characteristics outside tolerance limits has been observed, also some of the computer units have had several short stops due to faulty components. Except for that the performance of the field instrumentation and the computer installations has been satisfactory. A floating threshold procedure has been implemented in the Detection Processor. In the Event Processor some additional statistical tests have been included as a result of a study of signal-noise classification problems. A study of precursors to PP has been finished.
