Notes. A short sample of the results obtained by the Calern Asteroid Polarimetric Survey, since the beginning of operations and up to December 2021. The whole data table has been uploaded to the Centre de Données astronomiques de Strasbourg (CDS) (http://cdsads.u-strasbg.fr/). All the observations collected for each object are listed, specifying for each entry the object’s identification number, the epoch of observation (expressed as year, month, day and fraction of day), the phase angle, the value of the measured Pr, its error, and the filter used. As for the latter, it is most commonly the standard V filter, but in several cases also the B, R and I filters of the Johnson-Cousin system have been used. A few additional measurements in BRI colours taken since 2018 are not listed because they are still under reduction.
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.
