J/PASP/106/745      The Spectrum of IC 418              (Hyung+ 1994)

The Spectrum of the Planetary Nebula, IC 418 Hyung S., Aller L. H., and Feibelman W. A. <Publ. Astron. Soc. Pac. 106, 745, (1994)> =1994PASP..106..745H
ADC_Keywords: Planetary nebulae ; Spectra, ultraviolet Abstract: A detailed high spectral resolution study of the spectrum of IC 418 is made for the region 3650Å to 10050Å, using the Hamilton echelle spectrograph of Lick Observatory, and of the UV spectral region with archival International Ultraviolet Explorer (IUE) data.

Note on lam.obs: The observed wavelength in A corrected for the radial velocity, V_{rad} = 37.375 km/s. Note on k: The extinction coefficient, k_λ, as tabulated from equations given by Seaton (1979MNRAS.187p..73S) Note on I: the flux I(lam) relative to I(Hbeta) =100 corrected for interstellar extinction, C = log I(H beta)/F(H beta) = 0.21, a value derived by comparing reliable Balmer and Paschen lines. that is, the extinction at lambda 4861 is 0.21 dex.
