The following Excel spreadsheets contain versions of the Almagest star catalog:

• the data as found in the Almagest, including the textual star descriptions (from G. J. Toomer, Ptolemy’s Almagest , (London, 1984)), the matching real star names and coordinates from the Yale Bright Star Catalog.

• as above, but all star coordinates are adjusted for precession to 129 BC. For the Almagest stars, -2 2/3° is subtracted from the ecliptical longitude. Also included is the degree of the ecliptic rising, setting, or culminating as each star rises or sets, plus the degree of the ecliptic culminating when the star culminates.

• as above, but all coordinates are now equatorial (except for the degrees of the ecliptic, of course) and adjusted for 129 BC.

• as above, but all true coordinates are now ecliptical and adjusted for 1270 AD.

• as above, but all true coordinates are now equatorial and adjusted for 1270 AD.
