CURTATION
, the interval between a planet's distance from the sun, and the curtate distance.
From the foregoing article it is easy to find the curtate distance; whence the manner of constructing tables of curtation is obvious; the quantity of inclination, reduction, and curtation of a planet, depending on the argument of latitude. Kepler, in his Rodolphine Tables, reduces the tables of them all into one, under the title of Tabulæ Latitudinariæ.
