Abstract: Twofitlines is a tool developed within IRAF, optimized to be used with data containing multiple spectra along the spatial axis of the detector. A given spectral feature can be decomposed in one or several Gaussian components. The results are obtained in handy graphical and text formats. The error in the fitted parameters is estimated by successive fits to Montecarlo simulated spectra. An extra capability allows to measure useful asymmetry parameters for non-resolved spectral features.
