- (This table is largely experimental. Don't mess about with it - use the Talk page if you want to discuss the format, etc. There should eventually be a page explaining the format of such tables. The absolute magnitudes probably need to be changed a little to take into account the improved distance estimates, especially for Beta Caeli. The HD numbers are provided mainly so that additional data can easily be found from the Hipparcos catalogue http://astro.estec.esa.nl/Hipparcos/HIPcatalogueSearch.html.)
