The Luminosity Function Web Tool is a web interface written in PERL language by Dr. D. Cordier from ENSCR (France) in collaboration with Dr. S. Cassisi from Teramo Observatory (Italy), Dr. A. Pietrinferni from Teramo Observatory (Italy) and Dr. M. Salaris from Liverpool John Moores University (UK). This program uses only isochrones from BASTI database. This Web Tool is not a simple applet and as it is server side based, it is robust and fast.

Luminosity Function computed until:
RGB tip
Early-AGB
TP-AGB
Alpha (IMF exponent) (2.35 corresponds to the Salpeter's law)
Magnitude Bin (e.g. 0.15 mag, this bin has to be > 0.05 mag)
