Population Synthesis Program is a web interface written in PERL language by Dr. D. Cordier from ENSCR (France) in collaboration with Dr. S. Cassisi, Dr. A.Pietrinferni from Teramo Observatory (Italy) and Dr. M. Salaris from Liverpool John Moores University (UK). Through this interface the user can run the population synthesis code SYNTHETIC MAN described in Pietrinferni A., Cassisi S., Salaris M. and Castelli F. (2004, ApJ - vol. 612, 168), and updated in Cordier D., Pietrinferni A., Cassisi S., Salaris M.(astro-ph/0612669) . SYNTHETIC MAN determines the photometric properties of stellar populations with an arbitrary star formation history, taking into account photometric errors and unresolved binaries. The user receives a notification by e-mail when computations are completed. This web Tool is not a simple applet and, being server based, it is robust and fast.
This version is fully compatible with the previous one, and includes the possibility to choose among different Photometric Systems.

Random numbers generating
The random number generator is automatically initialized through the Web taking a seed from http://www.random.org (recommended option)
The random number generator is initialized with seeds provided by the user:
