10 Sep 2012 | Abstract: | We present an update of the visible and near-infrared colour database of
Minor Bodies in the Outer Solar System (MBOSSes), which now includes over 2000
measurement epochs of 555 objects, extracted from over 100 articles. The list
is fairly complete as of December 2011. The database is now large enough to
enable any dataset with a large dispersion to be safely identified and rejected
from the analysis. The selection method used is quite insensitive to individual
outliers. Most of the rejected datasets were observed during the early days of
MBOSS photometry. The spectral gradient over the visible range is derived from
the colours, as well as the R absolute magnitude M(1, 1). The average colours,
absolute magnitude, and spectral gradient are listed for each object, as well
as the physico-dynamical classes using a classification adapted from Gladman
and collaborators.
Colour-colour diagrams, histograms, and various other plots are presented to
illustrate and investigate class characteristics and trends with other
parameters, whose significances are evaluated using standard statistical tests.
The colour tables and all plots are also available on the MBOSS colour web page
this http URL which will be updated when new measurements
are published. | Source: | arXiv, 1209.1896 | Services: | Forum | Review | PDF | Favorites |
