OzDES Reverberation Mapping Program: Lag recovery reliability for 6-year
  CIV analysis
  We present the statistical methods that have been developed to analyse the
OzDES reverberation mapping sample. To perform this statistical analysis we
have created a suite of customisable simulations that mimic the characteristics
of each source in the OzDES sample. These characteristics include: the
variability in the photometric and spectroscopic lightcurves, the measurement
uncertainties, and the observational cadence. By simulating the sources in the
OzDES sample that contain the CIV emission line, we developed a set of criteria
that rank the reliability of a recovered time lag depending on the agreement
between different recovery methods, the magnitude of the uncertainties, and the
rate at which false positives were found in the simulations. These criteria
were applied to simulated light curves and these results used to estimate the
quality of the resulting Radius-Luminosity relation.We grade the results using
three quality levels (gold, silver and bronze). The input slope of the R-L
relation was recovered within $1\sigma$ for each of the three quality samples,
with the gold standard having the lowest dispersion with a recovered a R-L
relation slope of $0.454\pm 0.016$ with an input slope of 0.47. Future work
will apply these methods to the entire OzDES sample of 771 AGN.
