 ### Array Map
 
 The array map will display a color diagram to allow a visual check of the consistency of picks across multiple stations. This works by calculating the time difference of every onset to the earliest onset. Then isolines are drawn between stations with the same time difference and the areas between isolines are colored.  
-The result should resemble a color gradient as the wavefront rolls over the network area. Stations where picks are earlier/later than their neighbours can be reviewed by clicking on them, which opens the picking window.

 ## Usage
 
 ### Projects and Events
 
-PyLoT uses projects to categorize different seismic data. A project consists of one or multiple events. Events contain seismic traces from one or multiple stations. An event also contains further information, e.g. origin time, source parameters and automatic and manual picks.
-Projects are used to group events which should be analyzed together. A project could contain all events from a specific region within a timeframe of interest or all recorded events of a seismological experiment.

 ### Event folder structure
 
 PyLoT expects the following folder structure for seismic data:
 * Every event should be in it's own folder with the following naming scheme for the folders:
    ``e[id].[doy].[yy]``, where ``[id]`` is a four-digit numerical id increasing from 0001, ``[doy]`` the three digit day of year and ``[yy]`` the last two digits of the year of the event. This structure has to be created by the user of PyLoT manually.

+* These folders should contain the seismic data for their event as ``.mseed`` or other supported filetype
 * All automatic and manual picks should be in an ``.xml`` file in their event folder. PyLoT saves picks in this file. This file does not have to be added manually unless there are picks to be imported. The format used to save picks is QUAKEML.   
 Picks are saved in a file with the same filename as the event folder with ``PyLoT_`` prepended.
 * The file ``notes.txt`` is used for saving analysts comments. Everything saved here will be displayed in the 'Notes' column of the eventlist.
