Individual K-line profiles from elements of fine structure on the surface of the sun are calibrated absolutely. The continuum calibrations of Labs and Neckel and of Houtgast and Namba are considered, and the average K-profile is scaled to that of White and Suemoto. The ranges of intensities across a high-resolution spectrogram are tabulated for various parts of the line profile. Although the spatially-averaged value for K3 of 4.2% of the continuum corresponds to a brightness temperature of 4155 deg K, minimum and maximum values were 3980 and 4360 K, respectively. Similarly, K2v ranges from 4200 to 4560 K, and K2r from 4180 to 4460 K in small elements about 1 arc sec across.
Evaluation of spectrograms with a dispersion of 16.2 A/mm covering the spectral range from 3300 to 4900 A obtained for three early O stars and three early Of stars. Detailed line profiles of selected hydrogen and helium lines were obtained, and equivalent widths of nearly all visible lines were measured. Comparison of the spectroscopic properties between Of stars and O stars suggests that Of stars have lower surface gravities than do O stars. Comparison of their photometric properties confirms this suggestion. Hence present temperature scales for O5-O8 stars should not be applied to Of stars until the effect of gravity in determining spectral type has been determined. In addition, the spectra suggest that atmospheric models of Of stars should take into account spherical and hydrodynamic effects.
G61-29 is the first star discovered in which helium alone has been observed in emission. Three spectrograms of the star were obtained at the Lick 120-inch telescope. The most prominent spectral features in the blue region are the He I triplet lines at 4471, 4026, and 3889 A. All He I lines are extremely broad. The high proper motion of the star limits its maximum distance to about 200 pc or less if the star is gravitationally bound to the Galaxy.
Spectrograms of As electrodeless-discharge tubes operated in a field of 24,025 G have given Zeeman patterns for 232 As II spectral lines from 2361 to 10,556 A and yielded 80 Lande g factors, of which more than half are new. There is agreement between these and the g values calculated by least-squares fitting for single configurations or for multiconfigurations, where configuration interaction is noticeable. All of the measured g values as well as the energy levels are used in the fitting process.
