Slit Function Effects in the Direct Measurement of Absorption Line Half-Widths and Intensities

The strengths of absorption lines in the 2-0 band of carbon monoxide

“…Under these (4) conditions the instrumental slit corrections"•' to the strengths amount to no more than 3 per cent. Since this was within the experimental error, no instrumental corrections were applied and the strengths were obtained by direct integration.…”

“…Kostkowski and Bass [784] calculated A(v) exhaustively for the cases when the absorption line has the dispersion form and the apparatus function is described by the Gaussian distribution. A detailed theoretical study of the effect of the spectrometer on the spectral and total transmission measurement result has been carried out in the work of Nielsen, Thronton and Dolle [111], where it was shown for the first time that the total band absorption does not depend on the width of the instrument slit.…”
