3.3.8.3  :  Bertone2007a

This table contains the full result of the L-Galaxies run used in Bertone, De Lucia and Thomas 2007 (ADS).
Note that galaxies without stars have been assigned the value 99 for all their magnitudes.
Wind properties are assigned a value of zero when a galaxy is not blowing a wind (Bubble=0).
