The eventful life of galaxies  in low density environments

Narrow-band indices for simple stellar population models. The models include the original 21 indices of the Lick-IDS system (Worthey et al. 1994, ApJS, 94, 687) + 4 additional higher-order Balmer lines (Worthey & Ottaviani 1997, ApJS, 111, 377) + Near InfraRed indices from Cenarro et al. (2001, MNRAS, 326, 959). 

The SSps are based on 

      - Bertelli et al. 1994 isochrones (A&ASS, 106, 275)

      - Spectral libraries originally adopted by Bressan et al. (1994, ApJS, 94, 63)

        and revised by Tantalo et al. 1996 (A&A, 311, 361)

      - Fitting Functions of Worthey et al. 1994 (ApJS, 94, 687), 

        Worthey & Ottaviani 1997 (ApJS, 111, 377) and 

       Cenarro et al. 2002 (MNRAS, 329, 863)
