This introductory material is given in much more detail, with references to the papers of Huggins, Vogel, Jewell, Keeler and later papers of Campbell, in OsterbrockD. E., James E. Keeler pioneer American astrophysicist: And the early development of American astrophysics (Cambridge, 1984), 248–52. A complete paper summarizing all of Campbell's spectroscopic work on Mars, is DeVorkinD. H., “W. W. Campbell's spectroscopic study of the Martian atmosphere”, Quarterly journal of the Royal Astronomical Society, xviii (1977), 37–53.
