Rertrieves a window around S and SKS for stations within 40-75 or 85-105 degrees of earthquakes within 35-110 degrees of Tanzania

Events

Magnitude (mb) 5.5 with a distance of 35-110 deg from a central spot in Tanzania (35 lon, -5 lat) in the WHDF catalog. From 1990 to present with depth of at least 50 km.

Network

Any stations with broadband channels within a lat/lon box (30 to 40 lon, -15 to 0 lat). Only BH channels.

Waveform

Only want stations within either 40-75 degrees or 85 to 105 degrees of the earthquake, and a time window of 150 seconds around the S and SKS phases. The data should have the gain applied, be corrected to displacement, mean removed, trend removed, and filtered from 10 seconds to 10 hertz and saved as SAC files. The sac files should be in separate directories for each phase.
