The BASTI web based Isochrone/track Extractor
Isochrone/track Extractor 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 evolutionary tracks from Pietrinferni A., Cassisi S., Salaris M. and Castelli F. (2004, ApJ - vol. 612, 168). This Web Tool is not a simple applet and as it is server side based, it is robust and fast.
