QUACK Web Footed Interface

Welcome to the QUACK web footed interface. The web footed interface allows you to view seismic signal quality parameters measured by the QUACK framework. Quality parameters can be viewed in three different ways:

	In the Chart Data mode you can view charts (aka. tables) of quality control parameters for selected seismic channels and days.
	In the Plot Data mode you can view plots of the time variation of quality control parameters for selected seismic channels.
	In the Explore Data mode you can "drill" into data stored in IRIS's realtime collection systems and view day long plots of seismic signals. You can also view plots of quality control parameters.
	In the View Reports mode you can view pre-compiled custom reports. Available reports include: Dead Channels Report, Pressure Channel Report, Data Latency Report
	The filter allows you to filter out only the stations that you are interested in. Selection criteria include: (1) data collection system (bud/usra), (2) virtual networks and (3) channel activity. When filtering is active, the filter icon turns red. Help
