This catalogue shows the fitting results from the 
Haeussler et al 2007 fitting paper, for all real 41495
galaxies found in the GEMS images. This catalogue 
contains SExtractor and GALFIT (GIM2D results where not 
published in the paper as GALFIT was found to return more
reliable results simulation number.
Values of -9999 and/or -99 (if apparent) show that no values 
were derived for this parameter.

For further explanation (especially on how the errorbars are 
derived, they do NOT show errors returned by GALFIT!) 
please read the paper where these columns are discussed in detail
