Good morning,
I am Andrea Cannata, professor of geophysics at University of Catania (Italy). Sorry to bother you. I'd like to perform polarization analysis on seismic data (components BHZ, BHN, BHE) recorded in Antarctica by the following stations:

Network Station
AI BELA
AI ESPZ
AI SMAI
AI ORCD
AU MAW
G DRV
GE SNAA
GT VNDA
IU CASY
IU PMSA
IU SBA
PS SYO
YT BEAR
YT CLRK
YT DNTW
YT HOWD
YT MECK
YT MPAT
YT SILY
YT THUR

I was wondering whether the horizontal components of the seismic stations installed in Antarctica, downloaded by the iris website, have a peculiar orientation (for instance north taken to be along the prime meridian) or they have the same orientation as in the rest of the world.

Thanks in advance.

Best regards,

Andrea Cannata
