maximal acceptable simplification of fit model -- top be run with new bbb-merging threshold of 0.5
increased merging threshold for bbb uncertainties. Added bbb threshold for merging step to allow for a smooth transition between new merging and old merging. With this configuration new merging with merging threshold 0 should lead to the old results w/o merging
