An atlas of stellar spectra. I.

The first part of a new Atlas of Stellar Spectra is given here. In this paper are shown the spectra of 17 stars; all of the spectra include wavelengths beyond 10000 A, and some are printed so far as 4000 A in the blue. The spectra have been corrected for atmospheric extinction and have been transformed (approximately) to an equal-flux-per-unit-frequency basis. The equivalent widths of the hydrogen lines of four of the stars have been computed and tabulated. A complete description of the procedures and techniques used for the production of these spectra will be given in the second paper of this serses.
