Accessing data from a Taurus

Data recorded on a Taurus can be recovered either via the 100/10 Base-T Ethernet port or by removing the media and plugging it directly into a computer system. In either case, a standard web browser provides the user with the option of downloading selected events, lists of events or the complete data set. The latest Taurus software supports direct data download in MiniSEED, ASCII, SEGY and SEISAN. Retrieving data from the Taurus is designed to be convenient and fast. A standard browser serves as the user interface for data download. When retrieving data from a single Taurus via a network, the browser connects directly to the Apolo web server software running on the Taurus.  When retrieving data from multiple Taurus or single or multiple Taurus media connected directly to a computer, the browser connects to a local web server which in turn connects to the Taurus or media. Whether downloading data from a single Taurus or media, or from multiple Taurus or media, the following options are available.     Ad hoc data requests All data in a specific time period. User set parameters include start time, end time/duration, channels and duration of each file. Data requests can be for seconds, minutes, hours, days or months of data. Single files or data volumes. When downloading data from multiple units, users can specify whether the data are downloaded as individual data files or data volumes, a data volume containing all stations for a specific time period Data are available in MiniSEED, SEISAN, SEGY or ASCII Event data downloads Single event downloads from one or more Taurus. User specifies event time and duration. Multiple, list driven event downloads from one or more Taurus. Event list includes start time and duration for each event Single event downloads from one or more Taurus based on event origin time, location and phase. Taurus calculates the event arrival time at the Taurus loaction based on the IASPEI travel time tables and extracts the appropriate data Multiple, list drive event downloads from one or more Taurus. Taurus calculates the event arrival time at the Taurus loaction based on the IASPEI travel time tables and extracts the appropriate data Taurus will accept event lists in the following formats IRIS Search ASCII NEIC EPIC Search compressed NEIC Fingerd
