The average mean square error of a position, for the wholeCatalogue, is +/-0.009 s. The mean epoch of the catalogue is 1991.84.
| Minor planets and related objects. XVII - Five-color photometry of four asteroids
Asteroids (6), (14), (39), and (51) were observed at the Leiden SouthernStation. Only (39) Laetitia seems to show some variation in color (3% invisual-ultraviolet) correlated to the light curve. If a similar effectis present for (6) Hebe, it should only be present at small phaseangles. The light curves of (14) Irene and (39) Laetitia show lightvariations of a few percent of the rotational period indicating probablesurface macrostructure.
