Catalogue of asteroid polarization curves

Please make reference to: R. Gil-Hutton (2017) Catalogue of asteroid polarization curves, presented at "Asteroid, Comets, Meteors 2017", Montevideo, Uruguay.

Please take into account that the catalogue only includes observations made on filters V, R or similar. There are 5 groups:

• Group A: Asteroids with at least 5 measurements, excellent phase coverage and a polarization curve.
• Group B: Asteroids with at least 4 measurements, good phase coverage and a polarization curve.
• Group C: Asteroids with at least 3 measurements, regular phase coverage and a tentative polarization curve.
• Group D: Asteroids with at least 3 measurements and bad phase coverage.
• Group E: Asteroids with less than 3 measurements.

The phase coverage is indicated in the list of objects for each group and it is characterized by a flag which indicate the existence ("X") or not ("O") of a polarimetric measurement in eight bins of phase angle (0 to 3 degrees, 3 to 6 degrees, 6 to 9 degrees, 9 to 12 degrees, 12 to 15 degrees, 15 to 18 degrees, 18 to 21 degrees and larger than 21 degrees). The most urgent group to observe is the C since the asteroids in this group require only few observations to obtain a reliable polarization curve.

The list of papers, and their codes, from which the observations were obtained are:

a:	Lupishko (2022) Asteroid Polarimetric Database V2.0, NASA Planetary Data System.
b:	Cellino et al. (2020) Torino Ast. Polarimetry V1.0, NASA Planetary Data System.
c:	Castro-Chacón et al. (2022) PSS 213, 105428.
d:	Belskaya et al. (2022) AA 663, A146.
e:	Kiselev et al. (2022) MNRAS 514, 4861.
f:	Bendjoya et al. (2022) AA 665, A66.
g:	Geem et al. (2022) MNRAS 516, L53.
h:	Gil-Hutton (2023) AA submited.

The catalogue is updated to February, 2023.

Total number of polarimetric measurements: 6341.

Total number of asteroids with polarization curves: 295.

Total number of asteroids with polarimetric measurements: 795.

Group A:

In this group there are 113 asteroids. In this file you can find a summary for each asteroid with the minimum and maximum phase angles for which observations have been made, the total number of measurements, the flag indicating the phase angle coverage and a code indicating the group.

In the following table you can find for each asteroid a complete report, including a figure showing phase angle vs. Pr and the polarization curve, the list of available measurements with a reference to the original paper, the coefficients Coe1, Coe2 and Coe3 of the best fit and the polarimetric parameters of the object with their errors.
