Table of wavenumbers: Volume 1, 2000 A to 7000 A
From Extension of Tables: "Because of its range and size, this table of wavenumbers is in two volumes, Volume I presenting wavenumbers for all wavelengths between 2000 and 7000 A, and Volume II giving wave-numbers for all wavelengths from 7000 A to 10000000 A=1 mm. In some cases Volume I may suffice for ionic spectra, and in others Volume II may be adequate for molecular spectra, but in general both volumes will needed to cover the entire range of spectral wavelengths measured in standard air."

Oscillator Strengths and Transition Probabilities fro 3288 Lines of Fe I
Report of a homogeneous set of intensity-related data calculated for 3288 spectral lines of Fe I in the region from 2100 to 9900 angstroms. The quantities tabulated in the present monograph include log (g__), log (gf), gf,f,gA, and A. Since recent investigations do not support excitations corrections in the case of Fe I and certain other spectra, the present tabulation incorporates a removal of that normalization function. This recalculation affects the values for all lines whose upper energy levels lie above 46000 cm -1 and should significantly improve the internal consistency of the present data.

Reduction of Data for Piston Gage Pressure Measurements
Report discussing pressure measurements made with piston gages that are affected by gravity, temperature, pressure, and several other variables. For accurate determinations of pressure the calculations must take these variables into account. A general equation is developed and simplified procedures for calculating pressure are illustrated.
