SiFAP/TNG dataset of PSR J1023+0038

SiFAP/TNG observation fits file analyzed by Ambrosino, Papitto et al. (2017), "Optical pulsations from a transitional millisecond pulsar" (Nature Astronomy, https://www.nature.com/articles/s41550-017-0266-2, http://dx.doi.org/10.1038/s41550-017-0266-2)The times of arrival of optical photons reported in these files were corrected for a known systematic drift of the SiFAP clock (see Methods section in Ambrosino, Papitto et al.), and converted to the barycenter of the Solar System using the position of the source (RA = 155.94869665833°, DEC = 0.6446793083°). Times are reported in seconds since the MJDREF keyword (reported in the header of each of the four fits files).Please, address comments and requests to: [e-mail]
