Abstract

An elementary theory on the accuracy of wedge-density matching for logarithmically sectored spectra is given The results of the theory show that, other things being equal, the fractional error, as a result of wedge-density matching, in the measurement of intensity ratios of line pairs varies <i>inversely</i> as the intensity scale gamma of the emulsion employed, and within limits, is independent of both the magnification of the spectrum and the sector constant.
