Mainly the observations were performed at the Institute  of Astronomy (Kharkiv, Ukraine) and at the Astrophysics Institute      (Dushanbe, Tadjikistan).  For most asteroids the magnitude-phase       relations were obtained down to phase angles less than 1 deg. For some asteroids the magnitudes are presented in three (UBV) or four (BVRI)   standard spectral bands.", "identifier": "urn:nasa:pds:compil.ast.magnitude-phase", "issued": "2021-05-21", "keyword": ["multiple-asteroids", "none"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewBundle.jsp?identifier=urn%3Anasa%3Apds%3Acompil.ast.magnitude-phase&version=1.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "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": "KHARKIV ASTEROID MAGNITUDE-PHASE RELATIONS"}
