A catalogue of 2D photometric decompositions in the SDSS-DR7 spectroscopic main galaxy sample: preferred models and systematics

Understand

We present a catalogue of two-dimensional, point spread function-corrected de Vacouleurs, S\'{e}rsic, de Vacouleurs+Exponential, and S\'{e}rsic+Exponential fits of $\sim7\times10^5$ spectroscopically selected galaxies drawn from the Sloan Digital Sky Survey (SDSS) Data Release 7.

• Fits are performed for the SDSS r band utilizing the fitting routine GALFIT and analysis pipeline PYMORPH.
• We compare these fits to prior catalogues.
• Fits are analysed using a physically motivated flagging system.
