Final compilation of photometry of Uranus and Neptune, 1972-2016

摘要

Photometric observations of Uranus and Neptune made each year since 1972 at Lowell Observatory in the b (472 nm) and y (551 nm) filters of the Stromgren photometric system recorded the mainly seasonal variations of disk-integrated albedos of these objects. The measurements predate Voyager and Hubble Telescope multi-wavelength imaging and overlap more than a decade of ground-based adaptive optics near-IR imaging. This paper is a final archive and brief summarizing discussion of observations through 2016 and includes electronic tables of 360 observations of Uranus and 433 observations of Neptune.
