HiPERCAM/ULTRACAM observations of PSR J2051-0827
收藏资源简介:
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:<br> 1) orbital phase (in rotations, with phase = 0 corresponding to pulsar's ascending node),<br> 2) flux density (in erg cm<sup>-2</sup> s<sup>-1</sup> Hz<sup>-1</sup>)<br> 3) flux density uncertainty (in erg cm<sup>-2</sup> s<sup>-1</sup> Hz<sup>-1</sup>) For the HiPERCAM data, the columns are:<br> 1) MJD time<br> 2) orbital phase (in rotations, with phase = 0 corresponding to pulsar's ascending node),<br> 3) flux density (in erg cm<sup>-2</sup> s<sup>-1</sup> Hz<sup>-1</sup>)<br> 4) flux density uncertainty (in erg cm<sup>-2</sup> s<sup>-1</sup> Hz<sup>-1</sup>)
