(2016) [Journal article]
      Spatially varying depth and the characteristics of observing conditions, such as seeing, airmass, or sky background, are major sources of systematic uncertainties in modern galaxy survey analyses, particularly in deep ...

C.; Tarle, Gregory; Zuntz, J. (2015) [Journal article]
      We present a forward-modeling simulation framework designed to model the data products from the Dark Energy Survey (DES). This forward-model process can be thought of as a transfer function—amapping from cosmological/ ...
