IERS_Auto#

class astropy.utils.iers.IERS_Auto(data=None, masked=False, names=None, dtype=None, meta=None, copy=True, rows=None, copy_indices=True, units=None, descriptions=None, **kwargs)[source]#

Bases: IERS_A

Provide most-recent IERS data and automatically handle downloading of updated values as necessary.

The returned table combines the IERS-A and IERS-B files, with the data in the IERS-B file considered to be official values and thus superseding values from the IERS-A file at the same times.

Attributes Summary

iers_table

Cached table, returned if open is called without arguments.

Methods Summary

open()

This reads in the bundled IERS_A table (or the version of the file in the current working directory, if present - see IERS_A.read).

Attributes Documentation

iers_table = None#: Cached table, returned if open is called without arguments.

Methods Documentation

classmethod open()[source]#

This reads in the bundled IERS_A table (or the version of the file in the current working directory, if present - see IERS_A.read).

Subsequently, if values are requested which are more recent than the range of validity of the bundled table, an updated version of the table will be downloaded if the configuration setting astropy.utils.iers.conf.auto_download is set to True (default) and if the available version of this file is older than astropy.utils.iers.conf.auto_max_age days old.

If the configuration setting astropy.utils.iers.conf.auto_download is set to False then the bundled IERS-A table will always be used.

Returns:
