Data Extractor User Guide

The Station-based data extractor bundles segments of waveform data based on technologies, time range, geographic area and station names criteria specified in the Station-based Data Retrieval form . More information is available by clicking on the button next to the Technology field.
Once desired criteria are populated and the "Data Extractor" radio button is checked, clicking on the button will return a Data Request Review Form. This form allows users to refine the bundling criteria based on channel names, array data availabilities or inclusion of Station Metadata. An example is shown in Figure 1. Additional information is provided via popup tooltip.
