Webcorrelation analysis using the DCF (Edelson & Krolik 1988) and the MMD (Huf-nagel & Bregman 1992) techniques and statistically determined the significance of the time lags using Monte Carlo simulations (Peterson et al. 1998). We refer to Zhang et al. (1999) for the relevant details of such analysis. The result is an average lag of −2.7+1.9 WebBradley M.

WebOct 1, 1998 · Hence, the main technique for measuring the BLR scale is the calculate the cross correlation function (CCF) between the lines and the continuum, Foc, ( z) = J m L (t) Qt- r) dt It is customary to define the value of r corresponding to the peak or mass-centre of the CCF as the delay of that line on the continuum.
