Photometric Redshifts and Photometry Errors
D. Wittman, P. Riechers, V. E. Margoniner
We examine the impact of non-Gaussian photometry errors on photometric redshift performance. We find that they greatly increase the scatter, but this can be mitigated to some exten…

Photometric Redshifts and Signal-to-Noise
V. E. Margoniner, D. M. Wittman
We investigate the impact of photometric signal-to-noise (S/N) on the precision of photometric redshifts in multi-band imaging surveys, using both simulations and real data. We sim…

Probing the Relation Between X-ray-Derived and Weak-Lensing-Derived Masses for Shear-Selected Galaxy Clusters: I. A781
Neelima Sehgal, John P. Hughes, David Wittman +4
We compare X-ray and weak-lensing masses for four galaxy clusters that comprise the top-ranked shear-selected cluster system in the Deep Lens Survey. The weak-lensing observations…
