What is the convention of indicating energy and gamma intensity errors?

Hi guys,

Can somebody remind me what the convention of indicating energy and gamma intensity errors is?

For example, in www.nndc.bnl.gov, they use "1460.820 5 10.66 % 17 " respectively for energy and gamma inttensity of 40K decay information?

Sincerely yours.

Hi,

this is an interesting topic but how is ROOT involved?

Cheers,

Nothing to do with ROOT. That’ s why I put it under the general chat for an quick answer.
Example, www.nndc.gov website uses 1460.830 5 keV for energy and (10.66 % 17) in percentage for gamma intensity for 40K nuclide.

Does that mean 0.1066± (0.1066x0.17) , or not? For energy, does it mean 1460.830keV ± 0.005 or 1460.830keV ± (1460.830 x0.05) keV.
