We adopted the library of stellar spectra by Jones (1999). It consists
of spectra of 684 stars collected with the Coude-feed telescope at Kitt
Peak National Observatory. The spectra cover the region that goes from
3820 to 5410 
with a gap between 4500 and 4780 ,
with a resolution of 1.8 . More detailed information about
the spectral library can be found in Jones & Worthey (1995, hereafter
JW95), Jones (1999), Vazdekis (1999), and Paper I). The Jones spectral
library is very comprehensive, encompassing all spectral types and
luminosity classes that contribute relevantly to the integrated light
of early-type galaxies in the optical.
