pyLick#

pylick is Python tool to measure spectral indices from galaxy spectra. Currently, ~80 indices from the near-UV to the near-IR are included. New indices can be easily introduced. The uncertainties are evaluated using the signal-to-noise method proposed by Cardiel et al. (1998). Finally, the code includes useful plotting routines.
