astropy fails to download IERS-A table when offline #60

Open scriptorron opened 8 months ago

scriptorron commented 8 months ago

From time to time astropy wants to download the latest IERS-A table from internet. If the Pi is offline this will raise an error. The automated download can be disabled with:

from astropy.utils.iers import conf
conf.auto_max_age = None

Preferred solution is to replace astropy by the same library used in KStars. This would also remove the discrepancy between the positions calculated by KStars and astropy.

See more information about the IERS data download: https://docs.astropy.org/en/stable/utils/iers.html

Probably it is also needed to set:

astropy.utils.iers.conf.iers_degraded_accuracy = "ignore"

Make a configuration setting in the INI file to allow data download for setups with internet access.

I checked if I can replace astropyby the library (libnova) used in KStars. There are arguments against it:

Download of IERS data is disabled now.
