VIDEO meets MegaMorph: Deriving Photometric Redshifts from Consistently 
Measured Photometry

Photometric redshifts today are largely derived by using aperture photometry 
measurements that can be prone to observational effects, e.g. different 
PSFs/reslutions in different observed bands.
In this poster, we present a comparison of photometric redshifts using 
different techniques, especially magnitudes from light-profile fitting that 
take into account PSF effects.
We use MegaMorph to carry out consistent and physically meaningful, multi-band 
profile fitting and use the resulting magnitude measurements to derive 
photometric redshifts for a sample of ~1000 galaxies in the VIDEO survey. We 
compare the results to both spectroscopic redshifts available and to results 
using traditional aperture photometry.
