1. Present status of photometric parameters of asteroids Creator: Kahl Kristensen, Leif Format: bez média and svazek Type: model:article and TEXT Subject: asteroids, photometric data, and uncertain coefficients Language: Czech Description: The external accuracy of photometric parameters of asteroids is investigated by comparison of published lists. Absolute magnitudes are consistent at the ±0.1 mag level but phase coefficients are still rather uncertain. Rights: http://creativecommons.org/publicdomain/mark/1.0/ and policy:public
