Each line in the marker file represents a visual marker. There are three kinds of markers: event markers, phase markers, and basic markers.
basic and phase markers can be associated with a certain NET.STA.LOC.CHA name
basic and phase markers can either match a time instant or a time span
phase markers can be associated to an event marker
The rules how to parse these files are somewhat cumbersome. Use the library
functions pyrocko.marker.load_markers()
pyrocko.marker.save_markers(). The marker file format is subject to be
replaced by a YAML based variant.
