SUMMARY:MILES: population synthesis for the 21st century
DESCRIPTION:MILES: population synthesis for the 21st century\nDrs. Alexandr
 e  Vazdekis, Elena Ricciardelli, Jesús Falcón Barroso\n\nWe present the 
 new stellar population synthesis models based on the empirical stellar spe
 ctral library MILES, which can be regarded nowadays as standard in the fie
 ld of stellar population studies. The synthetic SEDs cover the whole optic
 al range at resolution 2.3 Å (FWHM). The unprecedented stellar param
 eter coverage of MILES allowed us to extend our model predictions from int
 ermediate- to very-old age regimes, and the metallicity coverage from supe
 r-solar to [M/H] = -2.3. Observed spectra can be studied by means of full 
 spectrum fitting or line-strengths. For the latter we propose a new Line I
 ndex System (LIS) to avoid the intrinsic uncertainties associated with the
  popular Lick/IDS system and provide more appropriate, uniform, spectral r
 esolution. We present a web-page with a suite of on-line tools to facilita
 te the handling and transformation of the spectra. Online examples with pr
 actical applications to work with stellar spectra for a variety of instrum
 ental setups will be shown. Furthermore we will also show examples of how 
 to compute spectra and colors with varying instrumental setup, redshift an
 d velocity dispersion for a suite of Star Formation Histories.
