20080307:
The s32.0 (solar 32 solar masses) has been updated in the pre-SN files, but not in the movies/animations.
Thanks to Christain Ott for noticing the problems with s32.0.

Analytically Estimated Accretion Data

We estimate the infall time scale as that resulting from 1/4 free fall acceleration (dust collapse) using the presupernova structure and velocity of the star (see table above). In collaboration with (and thanks to) Thomas Janka.
