Non-Standard Earthworm Modules in current use
- reftoew: receives packets from Reftek dataserver (dataserver software
from UNR), puts data into EW trace_ring, and outputs continuous SAC files.
Code written by D. Chavez under contract to the University of Utah.
- nsn_rcv: receives data feed from USNSN (currently 7 stations located
in montoring area). Code written by D. Chavez under contract to the University
of Utah.
- nsn_sta: writes SAC-format files for USNSN data locally. Code written
by D. Chavez under contract to the University of Utah..
- vdl: sends data feed (currently 8 analog-telemetered, short-period
and 2 digitally-telemetered BB stations) to USNSN. Code written by D. Ketchum,
USGS.
