GALFIT result for GEMS galaxies
Listed in IVOA Registry (Virtual Observatory)
In the context of measuring the structures of intermediate-redshift galaxies with HST ACS surveys, we tune, test, and compare two widely used fitting codes (GALFIT and GIM2D) for fitting single-component Sersic models to both simulated and real galaxy data.
Description
Our study focuses on the GEMS survey (Rix et al., 2004ApJS..152..163R) with the sensitivity of typical HST survey data, and we include our final catalog of fit results for all 41495 objects detected in GEMS.
Using simulations, we find that fitting accuracy depends sensitively on galaxy profile shape.
