The absorption spectrum of the P(8) and P(9) manifolds of the $\nu_{3}$ band of $CH_{4}$ have been recorded with the grating both two and four passed in order to compare the effects of the diffraction limit on the deconvoluted spectrum. Care was taken to record these spectra so their appearance was as similar as possible, i.e., same observed resolution, signal to noise and intensity. The two passed spectra were observed with a spectral slit width very close to the diffraction limit. We show the result of constrained deconvolution which clearly surpasses the theoretical limit of the grating. en_US dc.format.extent 124454 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title A COMPARISON OF SOME EFFECTS OF CONSTRAINED AND UNCONSTRAINED DECONVOLUTION en_US dc.type article en_US
