Real-time trace view.
scrttv visualizes real-time waveform data (see scrttv overview) of a defined window length (default=30 minutes) and of defined streams/stations (default is primary station channels). scrttv switches between two modi. In the normal mode the trace order is given by the configuration file. In the event mode the traces are sorted by epicentral distance to the latest origin received from the messaging. Additional to the waveform traces information about gaps, picks and the time of incoming origins are displayed.
scrttv overview
scrttv shows two tabs: the enabled and the disabled tab (see scrttv overview: Tab 1-2). Stations listed in the disabled tab are excluded from processing (e.g. picking). To move a station from one tab to another just drag and drop the trace to the new tab. An alternative solution is to double click on the trace label to disable a trace.
Normally, the raw data are displayed. Pressing f the predefined bandpass filter of third order from 0.5 Hz to 10 Hz, BW(3,0.5,10) is applied to the traces. Also zoom functions for the time and amplitude axis are provided.
artifical origin
In case the operator recognizes several seismic signals, an artificial/preliminary origin can be set by either pressing the middle mouse button on a trace or by opening the context menu (right mouse button) on a trace and selecting "Create artificial origin". The following pop-up window show the coordinates of the trace and the time the click was made on the trace. Pressing "Send" sends this origin to the LOCATION group. This artificial origin is received e.g. by scolv and enables an immediate manual analysis of the closest traces.

scrttv inherits global options.
Type: int
If greater than 0 then all traces for which the data latency is higher than this value are hidden. Default is 0.
Type: boolean
If enabled then all traces are sorted by distance when a new origin arrives. Default is true.
Type: boolean
If enabled, picks are shown. Default is true.
Type: string
Defines the filter to be used when filtering is activated. Default is BW(3, 0.5, 10.0).
Type: int
Defines the buffer size in seconds of the ring bu of each trace. Default is 1800.
Type: int
Time span in seconds to switch back to the last view after an origin caused resorting. The default is 15min. Default is 900.
Type: list:string
Defines a list of channels codes to be displayed. Each list item can contain wildcards at any position and the given list is intersected with all channels configured in inventory.
Note
streams.sort.* Configures an initial location (latitude, longitude) to be used for sorting the traces.
Type: double
Latitude of the initial location.
Type: double
Longitude of the initial location.
Note
streams.region.* Defines a region used for clipping requested stations.

show version information
Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it, eg scautopick -> scautopick2.
Load given plugins.
Run as daemon. This means the application will fork itself and doesn't need to be started with &.
Enable/disable self-shutdown because a master module shutdown. This only works when messaging is enabled and the master module sends a shutdown message (enabled with --start-stop-msg for the master module).
Sets the name of the master-module used for auto-shutdown. This is the application name of the module actually started. If symlinks are used then it is the name of the symlinked application.
Sets the name of the master-username of the messaging used for auto-shutdown. If "shutdown-master-module" is given as well this parameter is ignored.
Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug
Increase verbosity level (may be repeated, eg. -vv)
Quiet mode: no logging output
Limits the logging to a certain component. This option can be given more than once.
Use syslog logging back end. The output usually goes to /var/lib/messages.
Path to lock file.
Send log output to stdout.
Debug mode: --verbosity=4 --console
Use alternative log file.
Overrides configuration parameter connection.username.
Overrides configuration parameter connection.server.
Overrides configuration parameter connection.timeout.
Overrides configuration parameter connection.primaryGroup.
A group to subscribe to. This option can be given more than once.
Overrides configuration parameter connection.encoding.
Sets sending of a start- and a stop message.
List all supported database drivers.
The database connection string, format: service://user:pwd@host/database. "service" is the name of the database driver which can be queried with "--db-driver-list".
The configmodule to use.
Load the inventory database from a given XML file.
Do not use the database at all
List all supported record stream drivers
The recordstream source URL, format: [service://]location[#type]. "service" is the name of the recordstream driver which can be queried with "--record-driver-list". If "service" is not given "file://" is used.
Specify a file as record source.
Specify a type for the records being read.
