Thirty-eight stations along a single east-west profile of about 27 km. Acquisition used Phoenix MTU-5A receivers with MTC-150 induction coils; transfer functions were produced with Nord-West EPI-KIT 3.1 and 33 of the 38 are remote-referenced. Raw time series exist in the source release and are referenced, not hosted here.",
