The effective-rank of the covariance matrix needs to be tuned for each event using a diagnostic plot such as those shown above. The effective-rank of the covariance matrix needs to be tuned for each event using a diagnostic plot such as those shown above.

The above figures show the variation in $`\beta`$ with respect to the rank of the covariance matrix for off-source samples. The plots are produced using the off-source samples obtained for maximum likelihood samples ( reported in the above tables).

The above figures show the variation in $`\gamma`$ with respect to the rank of the covariance matrix for off-source samples. The intrinsic parameter of maximum likelihood samples (reported in the above tables) are used to produce the plots.
