Hobby-Eberly Telescope Spectra of Planetary-Nebula Nuclei with O VI Emission

HET spectra (.fits format) of 6 central stars of planetary nebulae showing O VI emission lines. Obtained with the LRS2 spectrograph of the Hobby-Eberly Telescope at McDonald Observatory. For each observation there are 2 spectra, one in the UV arm, and one in the Orange arm, of the LRS2 spectrograph. Absolute calibrations have been applied. These spectra are discussed in a forthcoming paper "Spectroscopic survey of faint planetary-nebula nuclei. I. Six new O VI} central stars," by H. E. Bond, K. Werner, G. Jacoby, and G. Zeimann, submitted to Monthly Notices of the Royal Astronomical Society.
