Luminosity Calculator

This is a very primitive tool to estimate the optimal fill length as a function of some parameters. It does not contain a real luminosity model. By assuming a fixed turn-around time it calculates the optimal fill length.
Thanks to Michi Hostettler for implementing the continuous crossing level anti-leveling and the beta* anti-levelling!
