I read on the documentation that option ‘G’ for a TProfile the following:
‘G’ Errors are 1./SQRT(Sum(1/sigma**2))
For example, this would be useful when all Y’s are experimental quantities
measured with different precision Sigma_Y.
say i want to evaluate the resolution of a detector, and its dependence on a quantity, say “(Pt_reco - Pt_true)/Pt_true” (and atfter that plot it against Pt, eta or phi),
my question is:
is ‘G’ the right quantity to fit a resolution ? it seems not to depend explicitly on the number of entries used …
thank you very much
