Physical conditions in the foreground gas of reflection nebulae: NGC 2023, vdB 102, and NGC 7023.

Abstract (from CDS):
An appendix describes checks on the usefulness of IUE NEWSIPS data for interstellar studies. Equivalent widths are compared with a previous analysis of IUE observations for interstellar gas toward 20 Aql. Excellent agreement is found with NEWSIPS results having smaller errors. A comparison of NEWSIPS data for C I toward X Per with data acquired with the Hubble Space Telescope shows similar levels of agreement in equivalent widths and that the derived column densities from IUE results are accurate to better than a factor of 2 for absorption lines of moderate strength.
