Simulations of the OzDES AGN Reverberation Mapping Project
  As part of the OzDES spectroscopic survey we are carrying out a large scale
reverberation mapping study of $\sim$500 quasars over five years in the 30
deg$^2$ area of the Dark Energy Survey (DES) supernova fields. These quasars
have redshifts ranging up to 4 and have apparent AB magnitudes between
$16.8<r<22.5$ mag. The aim of the survey is to measure time lags between
fluctuations in the quasar continuum and broad emission line fluxes of
individual objects in order to measure black hole masses for a broad range of
AGN and constrain the radius-luminosity ($R-L$) relationship. Here we
investigate the expected efficiency of the OzDES reverberation mapping campaign
and its possible extensions. We expect to recover lags for $\sim$35-45\% of the
quasars. AGN with shorter lags and greater variability are more likely to yield
a lag, and objects with lags $\lesssim$6 months or $\sim$1 year are expected be
recovered the most accurately. The baseline OzDES reverberation mapping
campaign is predicted to produce an unbiased measurement of the $R-L$
relationship parameters for H$\beta$, Mg II $\lambda$2798, and C IV
$\lambda$1549. However, extending the baseline survey by either increasing the
spectroscopic cadence, extending the survey season, or improving the emission
line flux measurement accuracy will significantly improve the $R-L$ parameter
constraints for all broad emission lines.
