download_IERS_A

astroplan.download_IERS_A(show_progress=True)

Download and cache the IERS Bulletin A table.

If one is already cached, download a new one and overwrite the old. Store table in the astropy cache, and undo the monkey patching caused by earlier failure (if applicable).

If one does not exist, monkey patch _get_delta_ut1_utc so that Time objects don’t raise errors by computing UT1-UTC off the end of the IERS table.

Parameters:

show_progressbool

True shows a progress bar during the download.
