Abstract:

The report covers the period 1 October - 31 December 1972 which is characterized by improving, estimating and simulating the array detection capability. All activities related to field work, repair and maintenance of field instrumentation are now located in a single facility at Stange close to Hamar. The operational performance of the field equipment has been satisfactory also in this reporting period. The implementation of the incoherent event detector in the software system has improved the arrays event detectability approximately 15 per cent. A daily bulletin is edited, and is solely based on event detector data. Observed and predicted NORSAR event detectability using data from the first half ot 1972 have been worked out. Also potential detectability improvements as a function of more flexible bandpass filtering have been investigated.
