In future releases, a canonical set of sites may be bundled into astropy for when the online registry is unavailable. Additions or corrections to the observatory list can be submitted via Pull Request to the [astropy-data GitHub repository](https://github.com/astropy/astropy-data), updating the ``location.json`` file.

This acts as a mapping (dict-like object) but with the important caveat that it's always transforms its inputs to lower-case. So keys are always all lower-case, and even if you ask for something that's got mixed case, it will be interpreted as the all lower-case version. cCsi|_g|_dSN)_lowercase_names_to_locations_namesselfr8lib/python3.9/site-packages/astropy/coordinates/sites.py__init__!szSiteRegistry.__init__cCsB||jvr4t||j}t|td}t|d|d|j|S)aF Returns an EarthLocation for a known site in this registry.
