VizieR Online Data Catalog: Calern Asteroid Polarisation Survey (Bendjoya+, 2022)
Abstract
The Calern Asteroid Polarimetric Survey (CAPS), a collaboration between the INAF, Astrophysical Observatory of Torino (Italy) and the Observatoire de la Cote d'Azur (Nice, France) has produced new asteroid polarimetric data for a number of years, and is one of the most important, currently active projects of asteroid polarimetry. The CAPS catalogue is a steadily growing source of information which can be exploited for different purposes, including but not limited to an updated calibration of the relations existing between different polarimetric parameters and the geometric albedo of the objects, and a study of classes of objects that can be most easily identified by means of polarimetric properties. Until now unpublished data, from the CASLEO (Complejo Astronomico El Leoncito) survey are also added to the catalogs.
The CAPS catalog includes the results obtained by the Calern Asteroid Polarimetric Survey since the beginning of operations (August, 2018), up to December, 2021. All the data 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. The CASLEO catalog lists, using the same format adopted for the CAPS data, a number of unpublished polarimetric measurements of asteroids obtained between 1995 and 2004, plus a small number of measurements obtained in 2013, using the 2.15m telescope of the Complejo Astronomico El Leoncito (CASLEO), managed by the Universities of La Plata, Cordoba and San Juan (Argentina), and the Argentinian scientific and technical research council (CONICET).The U, B, V, R and I filters are those of the Johnson-Cousin system.
