1. TERRAscope Seismograph Network:   [ TS ]

DATES OF OPERATION:  	20 Jul 1990 to Present

SEISMOMETER TYPE and ADC:
Streckeisen Model STS-2/VBB 3 component system.  Kinemetrics Model FBA-23 
for all low-gain channels.  ADC is Quanterra Model Q-680.

DIGITAL FORMAT:
24 bit integer data words for all broad band (20 sps), long period (1 sps), and 
very long period (0.1 sps) and ultra long period.  Range: +8,388,607 to 
-8,388,608 counts.
16 bit integer data words for very short period (80 sps) and mass position channels,
and all enviromental channels.  Range: +32,767 to -32,768 counts.

EVENT DETECTOR ALGORITHM:  
The Murdock event detector (Murdock, 1991) is used for the EL_ and the 
EDO components.

COMMENTS:
EDO and LDO are given in dymanic pressure.  Static pressure can be determined
from P = (count - 5.24)/15.83 mbar.
