A technique is presented for computationally enhancing the resolution of quasar emission lines. Quasar spectral data are normally reduced to wavelength-calibrated, sky-subtracted, flat-field spectra with a Poisson distribution about the mean. A straight line can be assigned to the reduced spectra once the lines are divided into a finite number of segment-intervals. The line is fitted with a least squares method and allows for abrupt slope and rate of slope change variations. High-deviance lines are sought out and removed and high deviance segments are ignored. A lower limit is found for the probabilithy of the presence of any specific line. It is found, in comparison with actual data, that selection of a 90 percent efficiency level is sufficient for deriving a complete, uncontaminated data set. Absorption lines are calculated and provided for the quasar 1146+11D.
