1. TERRAscope Seismograph Network:   [ TS ]

DATES OF OPERATION:  	21 Dec 1990 to Present

SEISMOMETER TYPE and ADC:
Streckeisen Model STS-1/VBB 3 component system.  Kinemetrics Model FBA-23 for very 
short period channels.  ADC is Quanterra Model Q-52K. 

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 channels.  Range: +8,388,607 to 
-8,388,608 counts.
16 bit integer data words for very short period (100 sps) and mass positions channels,
and all environmental channels.  Range: +32,767 to -32,768 counts.

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

COMMENTS:
EDO and LDO are given in dynamic pressure.  Static pressure can be obtained from
P=(Count-5.24)/15.83 mbar.
