KEV - STATION INSTRUMENTATION
3. Digital World Wide Standardized Seismograph System - DWWSSN: [ DW ]
DATES OF OPERATION: 14 Oct 1981 to 11 Mar 1987
Benioff Short Period vertical seismometer, Geotech Model 1051 for SHZ data. Sprengnether
long period seismometers (one vertical Model S-5007-V previously Model 201 and two horizontal
Model S-5007-H previously Model 100) which are used for both long period and mid period data.
16 bit integer data words for all components. Range: +32767 to -32768.
EVENT DETECTOR ALGORITHIM:
The event detector used for the SHZ channel was developed at the ASL and is not documented.
The mid-period channels are detected on a straight forward amplitude basis.

The Noise Study was done using 1992 data, consequently, it is only an estimation
for this generation of station instrumentation.
A description of the Digital World Wide Standardized Seismograph Network
(DWWSSN) can be found in Peterson et al (1982).
