Question from TON user: Edgar Kiefhaber (Edgar.Kiefhaber@iket.fzk.de)
What is the information included in brackets, i.e.: (+26-6)?
It says 1.08 +0.26 ~ 1.08 -0.06. The error limit is different.

For 82Se (2b-) ENSDF value is 1.08E+20 Y +26-6 but in my revised wallet cards
I am going to quote 0.83E+20 Y 12. One of the problems with 2b- decay is
there is more than one value depending upon the decay mode is 2b-0nu or
2b-2nu (nu is neutrino), for my latest revision of Wallet Cards (in progress)
I have decided to give the lower limit.
