############
Tabular data
############

Significant events discovered in data from gravitational-wave observatories are
stored in tabular datasets, typically describing astrophysical events, or
noise transients (glitches).

================
The `EventTable`
================

GWpy extends the (excellent) :ref:`astropy-table` from `astropy` by providing
the :class:`EventTable`.

This object extends the functionality of the regular `~astropy.table.Table`
with enhanced I/O to support gravitational-wave data, and utilities for
processing and plotting tables of events that contain GPS timestamps.

See the :any:`astropy-table` documentation for examples of how to create
custom tables, and much more.
The only thing to change if you want to use the `EventTable` instead of
the basic `Table` is the import::

    >>> from gwpy.table import EventTable
