Tabular data

Alongside the timeseries data produced continuously at the laboratories, a number of different sets of tabular data are generated, typically recording significant noise transients (glitches) or gravitational-wave events found in the data.

The Table and EventTable

GWpy provides two classes for handling tabular data.

gwpy.table.Table A class to represent tables of heterogeneous data.
gwpy.table.EventTable A container for a table of events

Note

The Table is just an import of the astropy.table.Table, provided for import convenience, see the Astropy documentation for full details on that (excellent) object).

The EventTable extends the functionality of the regular Table with multi-file input routines, and utilities for processing and plotting tables of events that contain GPS timestamps.

See the Data Tables (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
