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 individual 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 six real sources that contain the CIV emission line, we developed a set of quality criteria that ranks 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. Of these six sources, two were given a quality rating of 1, corresponding to our 'gold standard'. Lags were recovered at 223$\pm$56 and 378$\pm$104 days with redshifts of 1.93 and 2.74 respectively. Future work will apply these methods to the entire OzDES sample of $\sim$750 AGN.
