Description of the Asteroid Polarimetric Database bundle V2.0 ============================================================= Bundle Generation Date: 2022-01-20 Peer Review: 2022_Asteroid_Review Discipline node: Small Bodies Node Content description for the Asteroid Polarimetric Database bundle ================================================================= The Asteroid Polarimetric Database (APD) is compiled by D.F. Lupishko of Karazin Kharkiv National University, Ukraine. This database tabulates the original data comprising degree of polarization as a function of phase angle of the asteroid, and additional parameters where available. The data included are published asteroid polarimetry for which observation dates are available, and unpublished asteroid polarimetry data which are provided to Lupishko along with the dates of observation. The last column of the APD file is a reference code consisting of the publication year and name of the first author. The full citations for the papers may be found in the accompanying reference list file, apdrefs.csv, in the data directory. For unpublished data, the code Unpbl. along with the name of the observer is used. This version of the APD is current through November 15, 2021. Modification History ==================== This data set was first reviewed and ingested in 1996, and was updated in 1997 with additional polarimetric data published since then, as well as an added table of derived polarimetric parameters including polarization curves and polarimetric albedos of selected asteroids. In 1999, 2000, 2006, 2008, 2012, 2014, 2019, and 2022 the data set was updated again with additional polarimetric observations published since the previous version. The 2012 version (V7.0) adds 214 new observations of 45 asteroids. The additions include the 2004 Torino observations of Itokawa, which had been archived in a separate data set, EAR-A-I0066-3-ITOKAWAPOL-V1.0. Thus this version supersedes the Itokawa polarimetry data set. In 2012, the polarimetric curves table, apdcurv.tab, was moved from the data directory to the document directory because it has not been updated since 1999 and since then several more recent analyses have been published. In 2014, the data set was updated to version V8.0 with the addition of 332 new entries of polarimetric results from five additional papers. The new papers included are 1.

Parameters ========== The parameters tabulated in 'apd.csv' are asteroid number, asteroid name or provisional designation, observation date, fractional observation day, filter, phase angle, degree of polarization and its error, polarization position angle and its error, degree of polarization and position angle in the proper coordinate system measured from the perpendicular to the scattering plane, the position angle of the scattering plane, the observatory, and the publication associated with the entry. Ancillary Data ============== The entries in 'apd.csv' include a reference to the published paper in which the data appeared, and to the observatory and telescope where the observations were made. The full references of the papers cited may be found in the file 'apdrefs.csv' in the data directory. The file is in csv format and includes 3 columns: The first is the reference key from apd.csv, the second is the full citation, and the third is the DOI if available. A general compilation of asteroid polarimetry papers is also included in the file 'polrefs.txt' in the document directory. Note that the selection in this document is limited to references found in ADS. The telescopes and observatories are listed in the document 'polobs.txt'. A pdf document providing plots of polarization as a function of phase angle for typical asteroids of G, B, C, M, S, V, and E types, as well as a table of average albedos and polarization phase dependences for the main asteroid types, is included in the document directory. Caveats to the data user ======================== This is a compilation of asteroid polarimetry results from the published literature. The user is referred to the individual publications for information on the confidence level of any given observation.
