| Abstract: |
The Digitiser and astronomical plate Archive facility at the Royal
Observatory of Belgium (ROB) is involved in the EU FP7 ESPaCE
(European Satellite Partnership for
Computing Ephemerides) project to digitise the
photographic glass plates of the natural satellites of Mars,
Jupiter and Saturn taken with the USNO 26 inch refractor by Dan
Pascu over a period of 30 years. Also some plates of Pluto taken
at USNO Flagstaff, at Lowell Observatory and at the Pulkovo
Observatory are being digitised, in order to estimate the
astrometric precision obtainable from the fitted positions in the
digitised images and the improvement this has on the planetary
ephemerides. The correction of the optical distortion caused by
the actual objective/detector unit of the ROB digitiser is
presented in detail. |
