# call_wget_gmag.ksh - This script sets the arguments

#
# July 19, 2013 clrussell@igpp.ucla.edu
# This script handles all ground based magnetometer networks that retrieve
# gmag data using a wget. Previously there were scripts for each network. The
# scripts have been combined into this one generic wget script. Currently
# networks that use wget include, usgs, maccs, lrv, intermagnet, greenland, and
# antarctica. This is not a difinitive list and may change.
#
# NB: it is intended that this script be run on gaia2 as the wget log file 
# formats differ between machines and wget_intermagnet_gmag relies on 
# information within the log file.
