The recording setup for data in step_table_galperin_and_xyz.mseed is:
- two Trillium Compact 120s on a step table
- first Trillium oriented towards North and recording original Galperin
components UVW (thus U is due East)
- second Trillium is rotated 25 degrees counter-clockwise from North (thus X is
at azimuth (90-25 = 65 degrees)
So for use in obspy.signal.rotate.rotate2zne the following azimuth and dip
setup should be used:
az_u = 90.0
dip_u = -(90.0 - 54.7)
az_v = 330.0
dip_v = -(90.0 - 54.7)
az_w = 210.0
dip_w = -(90.0 - 54.7)
az_x = 65.0
dip_x = 0.0
az_y = 335.0
dip_y = 0.0
az_z = 0.0
dip_z = -90.0
