Patent ID: 7083415

Claim:
A process for converting equatorial coordinate data of individual stars and objects of the heavens, and for any heavenly body in the skies, wherein said heavens include the group of twelve traditional zodiac constellations, to ecliptic coordinate data, in celestial longitude and celestial latitude, comprising: utilizing equatorial coordinate data of individual stars and objects, wherein said equatorial coordinate data comprises celestial position in right ascension, α, and declination, δ, which further comprises, utilizing said right ascension data in degree of 360 proceeding east from equatorial system origin at vernal equinox, if in sidereal hours converting to degree of 360, utilizing said declination data in degree north (+) or south (−); calculating said latitude, β, from said equatorial data by: β=arc sin (−cos δ sin α sin ε+sin δ cos ε), wherein ε, the obliquity of the ecliptic, in degrees; calculating said longitude, λ, from said α, δ and β data by: λ=arc cos((cos δ cos α)/cos β), which further comprises if said stars and said objects utilizing right ascension data of between 180 and 360 degrees, calculating said longitude, λ, from said α, δ and β data by: λ=360−arc cos((cos δ cos α)/cos β); generating said ecliptic coordinate data, in said β and λ; utilizing a computer or calculator having an iterative equation solver function, coding said conversion formulae into said computational device, and operating said conversions, wherein first solving for latitude, then solving for longitude; cataloguing the ecliptic coordinate positions of the group of the individual stars and objects configuring a heavenly constellation in celestial longitude and celestial latitude.
