VizieR Online Data Catalog: Irregular planetary satellites colors & shapes (Graykowski+, 2018)

The data were collected over nine nights between 2008 March and 2015 December at the W. M. Keck Observatory on Mauna Kea, Hawaii using the LRIS instrument on the 10 meter Keck I telescope (Oke et al. 1995PASP..107..375O, Table 2). The data used were all taken under photometric conditions with the telescope tracked at non-sidereal rates to follow the motion of each satellite. Most satellites were observed on multiple nights in order to check for repeatability of the measurements. We used the B, V, and R filters, for which the central wavelengths, λ_c, and full-widths at half maxima, FWHM, are B (4370 Å, 878 Å), V (5473 Å, 948 Å) and R (6417 Å, 1185 Å). The images were flat-fielded using composites of images recorded from an illuminated patch inside the Keck dome and photometrically calibrated using observations of stars with Sun-like colors from Landolt (1992, Cat. II/183).
