Illustration of emission-line detection with matched filtering. Top: observed flux of V190 in NGC 6266 with Hα emission and the fitted spectral model. Bottom: Hα emission line is still present in the residuals, as well as an absorption line at 6700 Å which is only found in the models. The convolution with a Gaussian increases the emission line above the threshold calculated from the mean absolute deviation of the residuals.
