The database contains 2653 measurements of linear and circular polarization for 65 comets since 1940. The narrow-band and broad-band measurements within the spectral region 0.3-3.5 micron are presented. The ranges of phase angles, helio- and geocentric distances of comets are 0.4-122 deg, 0.6-4.8 AU and 0.03-4.9 AU, respectively. We have compiled 64 references to the published papers and some unpublished sources. The data are presented in a tabular format (ASCII code). The database can be used as the observational basis for detailed theoretical modeling, interpretation of the phase-angle and spectral dependence of polarization, classification of comets, and for selecting future space-mission targets.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.ear-c-compil-5-db-comet-polarimetry-v1.0_xdyf-936n", "issued": "2018-06-26", "keyword": ["comet", "support-archives"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=EAR-C-COMPIL-5-DB-COMET-POLARIMETRY-V1.0", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "DATABASE OF COMET POLARIMETRY, V1.0"}
