cross section of dataset with several samples

Dreat Giancarlo,

At this stage, it may be better to add them as two different dataset, possibly with the same color lines in the plot. This is at least what I would do.

Cheers,

Benj

Is there a way to correctly retrieve the correct cross section for the merged dataset, instead of just the average cross section (which is ok only if the two samples have the same xsec)?

Dear Benjamin,

Thanks, but this solution doesn't work for me, one sample is the negative
interference between signal and background, picked up collecting terms in
the relevant Alfa strong expansion of the squared amplitude.
