exception MarkerOneNSLCRequired

class Marker(nslc_ids, tmin, tmax, kind=0)

General purpose marker GUI element and base class for EventMarker and PhaseMarker.

Parameters

• nslc_ids – list of (network, station, location, channel) tuples (may contain wildcards)

• tmin – start time

• tmax – end time

• kind – (optional) integer to distinguish groups of markers (color-coded)

static save_markers(markers, fn, fdigits=3)

Static method to write marker objects to file.

Parameters

• markers – list of Marker objects

• fn – filename as string

• fdigits – number of decimal digits to use for sub-second time strings (default 3)

static load_markers(fn)

Static method to load markers from file.

Parameters

filename – filename as string

Returns

list of Marker, EventMarker or PhaseMarker objects

set(nslc_ids, tmin, tmax)

Set nslc_ids, start time and end time of Marker.

Parameters

• nslc_ids – list or set of (network, station, location, channel) tuples

• tmin – start time

• tmax – end time

set_kind(kind)

Set kind of Marker.

Parameters

kind – (optional) integer to distinguish groups of markers (color-coded)

get_tmin()

Get start time of Marker.

get_tmax()

Get end time of Marker.

get_nslc_ids()

Get marker’s network-station-location-channel pattern.

Returns

list or set of (network, station, location, channel) tuples

The network, station, location, or channel strings may contain wildcard expressions.

match_nsl(nsl)

See documentation of pyrocko.util.match_nslc().

match_nslc(nslc)

See documentation of pyrocko.util.match_nslc().

one_nslc()

If one nslc_id defines this marker return this id. If more than one nslc_id is defined in the Marker`s *nslc_ids* raise :py:exc:`MarkerOneNSLCRequired.

copy()

Get a copy of this marker.

class EventMarker(event, kind=0, event_hash=None)

GUI element representing a seismological event.

Parameters

• event – A pyrocko.model.Event object containing meta information of a seismological event

• kind – (optional) integer to distinguish groups of markers

• event_hash – (optional) hash code of event (see: pyrocko.model.Event.get_hash())

get_event()

Return an instance of the pyrocko.model.Event associated to this EventMarker

class PhaseMarker(nslc_ids, tmin, tmax, kind=0, event=None, event_hash=None, event_time=None, phasename=None, polarity=None, automatic=None, incidence_angle=None, takeoff_angle=None)

A PhaseMarker is a GUI-element representing a seismological phase arrival

Parameters

• nslc_ids – list of (network, station, location, channel) tuples (may contain wildcards)

• tmin – start time

• kind – (optional) integer to distinguish groups of markers (color-coded)

• event – a pyrocko.model.Event object containing meta information of a seismological event

• event_hash – (optional) hash code of event (see: pyrocko.model.Event.get_hash())

• event_time – (optional) time of the associated event

• phasename – (optional) name of the phase associated with the marker

• polarity – (optional) polarity of arriving phase

• automatic – (optional)

• incident_angle – (optional) incident angle of phase

• takeoff_angle – (optional) take off angle of phase

get_event()

Return an instance of the pyrocko.model.Event associated to this EventMarker

load_markers(filename)
