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.

Filtering

scrttv allows filtering of waveforms. The hotkey f can be used to toggle the list of filters pre-defined in filters. Note that the list of filters defined in filters overwrites filter. Activate autoApplyFilter to filter all traces at start-up of scrttv with the first filter defined in filters.

~/.seiscomp3/scrttv.cfg

scrttv inherits global options.

maxDelay

Type: int

Unit: s

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. This is only being used if filters is not set otherwise it is overridden. This option is mainly for backward compatibility. 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. If defined then this filter list is used exclusively and the filter option is ignored.

autoApplyFilter

Type: boolean

Activates the first filter of the configured filter list after startup. This is equivalent to pressing ‘f’. Default is false.

bufferSize

Type: int

Unit: s

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

allTracesInitiallyVisible

Type: boolean

If set to true all traces will be visible on application startup independent of data availability. Default is false.

autoResetDelay

Type: int

Unit: s

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 (ex : PF.BON.00.HHZ) to be displayed. Each list item can contain wildcards at any position and the given list is intersected with all channels configured in inventory.

streams.blacklist

Type: list:string

If not empty then all stream patterns are part of the blacklist. The blacklist is only active if “streams.codes” is omitted and the default stream list according to the bindings is to be shown. Each pattern can include wildcards (either ? or *). The pattern is checked against the channel id which is a concatenation of network code, station code, location code and channel code separated with a dot, e.g. “GE.MORC..BHZ”.

streams.rows

Type: integer

Number of rows to show at once in one windows. If more traces than rows are loaded, the are accessible by a scroll bar.

Note

streams.sort.* Configures an initial location (latitude, longitude) to be used for sorting the traces.

streams.sort.latitude

Type: double

Unit: deg

Latitude of the initial location.

streams.sort.longitude

Type: double

Unit: deg

Longitude of the initial location.

Note

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

streams.region.lonmin

Type: double

Unit: deg

Minimum longitude.

streams.region.lonmax

Type: double

Unit: deg

Maximum longitude.

streams.region.latmin

Type: double

Unit: deg

Minimum latitude.

streams.region.latmax

Type: double

Unit: deg

Maximum latitude.

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.
