cutout_fits.casda.casda_login(username: str | None = None, store_password: bool = False, reenter_password: bool = False) → astroquery.casda.core.CasdaClass

Login to CASDA.

Parameters:

  • username (str | None, optional) – CASDA username. Defaults to None.

  • store_password (bool, optional) – Stores the password securely in your keyring. Defaults to False.

  • reenter_password (bool, optional) – Asks for the password even if it is already stored in the keyring. This is the way to overwrite an already stored passwork on the keyring. Defaults to False.

Returns:

CASDA class

Return type:

CasdaClass
