scrttv

Real-time trace view.

Description

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

An example of scrttv and the dialog window to set preliminary origin. Tab 1-2 = enable/disable tab; Counts = maximum counts of a stream; Info = stream information (station, network and channel code); Filter = filter status of the traces; Status = connection status.

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.

~/.seiscomp3/scrttv.cfg

scrttv inherits global options.

maxDelay

Type: int

If greater than 0 then all traces for which the data latency is higher than this value are hidden. Default is 0.

resortAutomatically

Type: boolean

If enabled then all traces are sorted by distance when a new origin arrives. Default is true.

showPicks

Type: boolean

If enabled, picks are shown. Default is true.

filter

Type: string

Defines the filter to be used when filtering is activated. Default is BW(3, 0.5, 10.0).

filters

Type: list:string

Defines a list of filters that is cycles through when pressing 'f'. This options supersedes the filter option. If not defined then filter is used instead.

bufferSize

Type: int

Defines the buffer size in seconds of the ring bu of each trace. Default is 1800.

autoResetDelay

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.

streams.codes

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.

streams.sort.latitude

Type: double

Latitude of the initial location.

streams.sort.longitude

Type: double

Longitude of the initial location.

Note

streams.region.* Defines a region used for clipping requested stations.

streams.region.lonmin

Type: double

streams.region.lonmax

Type: double

streams.region.latmin

Type: double

streams.region.latmax

Type: double

Command-line

Generic

-h, --help

show help message.

-V, --version

show version information

--config-file arg

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.

--plugins arg

Load given plugins.

-D, --daemon

Run as daemon. This means the application will fork itself and doesn't need to be started with &.

--auto-shutdown arg

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).

--shutdown-master-module arg

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.

--shutdown-master-username arg

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

--verbosity arg

Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug

-v, --v

Increase verbosity level (may be repeated, eg. -vv)

-q, --quiet

Quiet mode: no logging output

--component arg

Limits the logging to a certain component. This option can be given more than once.

-s, --syslog

Use syslog logging back end. The output usually goes to /var/lib/messages.

-l, --lockfile arg

Path to lock file.

--console arg

Send log output to stdout.

--debug

Debug mode: --verbosity=4 --console=1

--log-file arg

Use alternative log file.

Messaging

-u, --user arg

Overrides configuration parameter connection.username.

-H, --host arg

Overrides configuration parameter connection.server.

-t, --timeout arg

Overrides configuration parameter connection.timeout.

-g, --primary-group arg

Overrides configuration parameter connection.primaryGroup.

-S, --subscribe-group arg

A group to subscribe to. This option can be given more than once.

--encoding arg

Overrides configuration parameter connection.encoding.

--start-stop-msg arg

Sets sending of a start- and a stop message.

Database

--db-driver-list

List all supported database drivers.

-d, --database arg

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".

--config-module arg

The configmodule to use.

--inventory-db arg

Load the inventory from the given database or file, format: [service://]location

--db-disable

Do not use the database at all

Records

--record-driver-list

List all supported record stream drivers

-I, --record-url arg

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.

--record-file arg

Specify a file as record source.

--record-type arg

Specify a type for the records being read.
