For specific information of GIM2D parameters, we refer the reader to Simard et al. 2002. Bad and undefined values are marked as -1 or -99.989998 Some tags represent different quantities for different catalogs. For example, the repx tag represents the galaxy effective radius for the single Sersic fit, but represents the bulge effective radius for the n=4 and n=2 bulge + disk fits. For these types of tags, the description will indicate 'galaxy/bulge'. (The Sersic index tag, nb, falls under this category, but for the bulge+disk fits, the bulge Sersic index is set to either n=4 or n=2, as the name of the fit suggests.) Note that repx is given in pixels, in order to convert into a physical unit, one must do the following: repx*.03*hscale where .03 represents the conversion from pixel to arcsecond, and the hscale is they physical scale that converts arcsecond to kpc, it is based either on the spectroscic redshift or the photometric redshift, depending on the redshift quality code. The tags, rhlpxV and rhlpxI, also represent galaxy half-light radius, but we suggest to use repx from the single Sersic fit for galaxy half-light radius. Redshift type: For ZQ > 2, the redshift, under the tag 'z', is a good spectroscopic redshift. for ZQ < 3, the redshift is a photometric redshift from Huang et al., in prep.

catalog (since we need bulge or disk component to get these quantities). The columns numbers diverge between the single Sersic catalog and the n=4 and n=2 catalog starting at column 133, where the starred numbers represent the column numbers of the n=4 and n=2 catalog, while the un-starred column numbers represent those of the single Sersic catalog.
