Description:
    This directory contains movies in mpeg format which show models for the
    time evolution of the Hertzsprung-Russell diagram of a very young open
    cluster between 0 and 30Myr. Four different star formation scenario's
    are considered, (a) instantaneous star formation, (b) constant rate of star
    formation with time, (c) increasing rate of star formation, and (d)
    decreasing rate of star formation. For the latter three scenario's, models
    for a duration of the star formation episode {delta}t of 0.1, 1.0 and 10Myr
    are computed.
