Aladin-light sonification prototype, very rough outline.
Some stars have 'proper' IAU names, and these are resolved from the identifiers list we get back from SIMBAD.
Many return as their default name the Bayer designations (e.g. 'β Cephieid').
However, these are prepended with a 3-letter object type code (e.g. V*),
use a custom three-letter greek code (e.g. bet) and a three-letter constellation abbreviation (e.g. cep),
for a resulting name like V* bet cep.
We detect these using the list of object types from SIMBAD here. If it's updated new JSON needs to be derived from it:
- Download the types as 2
.csvfiles, and placeotypes_nodes.csvin thedata/folder. - Run
scripts/otypes_nodes_to_json.pyto convert them to.jsonformat. - Copy the contents of
otypes.jsoninto the javascript source asconst otype_to_type.
Once detected, we drop the object type and expand the abbreviations using:
- Constellation abbreviations from ViZier via AstroPy here. These are stored in astropy_constellations.json, and in the javascript source as
const constellation_abbreviations. - Greek letter codes from SIMBAD here. These are converted to a mapping by hand and stored in english_to_greek.
