\title{ Approximating photo-z PDFs for large surveys }

\maketitlepre

\begin{abstract}

Upcoming and ongoing galaxy surveys will produce redshift probability distribution functions (PDFs) in addition to traditional photometric redshift (photo-$z$) point estimates.  However, the storage of photo-$z$ PDFs may present a challenge as the dataset size increases, as we face a trade-off between the accuracy of subsequent science measurements and the storage cost. We investigate a number of different PDF approximations, using metrics that quantify performance in both large scale structure and weak gravitational lensing studies. In the process, we present \texttt{qp}, a Python library enabling the evaluation of various approximations of 1-dimensional PDFs, as suitable for photometric redshifts.
