Latest Assessment of Seismic Station Observations (LASSO)

View groups of MUSTANG metrics designed to examine specific aspects of a seismic station's performance. Groupings focus on seismometer component channels and are available by Virtual Network.

Create a customized view of MUSTANG metrics, with the ability tune the parameters used to assemble the network-station-channel-metric display.

Click to select metric(s) to display.
Hold [control] (PC) or [command] (Apple) to make multiple selections or hold [shift] (any platform) to select metrics en masse.
Enter "*" for all or use single network code, e.g. "II". "*" not recommended due to size of potential return
Enter "*" for all or station code, e.g. "BORG".
Enter "*" or location code, e.g. "00".
Enter "*" or wildcard with "?", e.g. "VM?".
Enter "*" for all; "M" is highly recommend.

This tutorial has been developed as a guide on the main features of LASSO and how to effectively use this software to assess the quality of seismometer data and metadata. The "Basic" and "Advanced" modes, and their various settings, are described along with a handful of examples relevant to each case.

The most current version of the tutorial can be downloaded as a pdf Tutorial.
