A year is the time between two recurrences of an event related to the orbit of the Earth around the Sun. ... Inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit and is the angular distance of the orbital plane from the plane of the reference (usually planets equator or the ecliptic), stated in degrees. ... In astrodynamics, under standard assumptions any orbit must be of conic section shape. ... For the geometric term, see diameter. ... A kilometre (American spelling: kilometer), symbol: km is a unit of length in the metric system equal to 1000 metres (from the Greek words χίλια (khilia) = thousand and μέτρο (metro) = count/measure). ... In astronomy, a rotation period is the time an astronomical object takes to complete one revolution around its rotation axis. ... The hour (symbol: h) is a unit of time. ... In astronomy the term spectral class refers to classifying objects according to their spectral lines, which indicate an objects chemical composition. ... C-type asteroids are carbonaceous asteroids. ... In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standardized distance away. ...

RASNZ Occultation Section - Planetary Occultation Results (4854 words)
The author is unaware of the length of the occultation observed by Charlie Smith.
As Dunham notes in the text of the article, the fit to the ellipse is relatively loose and that the most significant result is that (48) Doris is an extremely irregular shaped object.
Of course it is very unlikely that the same profile of (48) Doris was observed in this instance as that seen from South Africa 25 months earlier but this observation does go some way of confirming the earlier conclusion.
