- RA = Remotely Accessible
- STS = Wielandt and Streckeisen
IRIS GSN Definitions
- VBB = Very Broad Band (Steckeisen STS-1, Teledyne KS54000, or Teledyne KS36000i) @ 20 sps, 1 sps, 0.1 sps & 0.01 sps continuous
- BB = Broad Band (Streckeisen STS-2) @ 20 sps, 1 sps, 0.1 sps & 0.01 sps continuous
- HF = High Frequency (Teledyne GS-13, Streckeisen STS-2, or Guralp CMG-3)
@ 100 sps triggered; 40 sps continuous planned for 94/95
- LG = Low-Gain accelerometer (Kinemetrics FBA-23) @ 100 sps triggered, 1 sps continuous
- 24b = Data acquisition system with 24-bit digitizer
- 144dB/DG = Data acquisition system with 16-bit digitizer with both high and low gain channels for 144dB dynamic range
Federation Network Station
A subset of more than 130 global stations of the
Federation of Digital Broad-Band Seismograph Networks or FDSN.
They are chosen on the basis of hardware standards (VBB or BB and VLP, 3-component, dynamic range greater than 100db),
noise characteristics, geographical location, and status (installed or
installation imminent). The FDSN station and their description can be found in
the FDSN Station Book.
