Description:
    Deep CCD spectra of the planetary nebula NGC 7027, taken over the
    range 654-1046nm at a spectral resolution of the order of 0.1nm, are
    presented. About 465 different lines are detected and intensities are
    provided for 405 features. A total of 680 emission lines is
    considered.
