Notes. The columns contain asteroid name, J2000 ecliptic coordinates λp, βp of the spin solution, with mirror pole solution in the second row, sidereal rotation period P, and the deviation of model fit to those light curves (including fit to sparse data). The next part of the table details the radiometric solution for combined data: surface-equivalent size D, geometric albedo pV, thermal inertia Γ in J m−2 s−1∕2 K−1 (SI) units, and the reduced chi-square of the best-fit (). The last two columns give average heliocentric distance of thermal infrared observations rhel with the standard deviation, and thermal inertia normalised to 1 AU ΓAU calculated according to Eq. (1). Numbers in italics mark the pole solution of (667) Denise clearly rejected by occultation fitting.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
