HiPERCAM/ULTRACAM observations of PSR J2051-0827

Optical observations of PSR J2051-0827 taken by the high-speed triple-beam CCD camera ULTRACAM on the William Herschel Telescope, and by the high-speed quintuple-beam CCD camera HiPERCAM on the Gran Telescopio Canarias. As presented in Dhillon et al. 2022 (MNRAS, in press, https://arxiv.org/abs/2208.09249). The letter after the underscore in each file name represents the observing filter for that specific file. For the ULTRACAM data, the columns are: 1) orbital phase (in rotations, with phase = 0 corresponding to pulsar's ascending node), 2) flux density (in erg cm-2 s-1 Hz-1) 3) flux density uncertainty (in erg cm-2 s-1 Hz-1) For the HiPERCAM data, the columns are: 1) MJD time 2) orbital phase (in rotations, with phase = 0 corresponding to pulsar's ascending node), 3) flux density (in erg cm-2 s-1 Hz-1) 4) flux density uncertainty (in erg cm-2 s-1 Hz-1)
