bw_relp
bw_relp is an earthquake location algorithm designed specifically for locating earthquakes at local and regional distances using phase onset times and onset azimuths recorded by relatively sparse network of three-component broadband stations. An adaptive, migrating grid search algorithm is used to locate the hypocenter.

psd
psd is a background noise acceleration Power Spectral Density (PSD) estimation algorithm designed specifically to extract all necessary information and data for calculating the PSD estimates from a SEED data volume. It is an exportable version of the acceleration PSD algorithm that has been in routine use at the Berkeley Seismological Laboratory (BSL) for approximately the past decade.
