4. Current issues with RULER Tibor Kibèdi, Dep. of Nuclear Physics, Australian National UniversityNSDD 2015, IAEA, 20-24-Apr-2015 NSDD/IAEA: 3.2a (Aug-6-2007; T.W. Burrows) Isomer evaluation (ANU/ANL): 4.1c (12-Jun-2014) Problems:  Complicated logic  Related parameters stored at different places  Uncertainty propagation: analytical approach; ad hock, nested branches based on numerical values Modifications  ENSDF type: Value, uncertainties (numerical and character) stored together  Simplified logic  Added functionality:  ICC calculated for mixed and pure multipolarities to deduce B(  L) and B(  ’L’)  LaTex output for ADNDT

5. Value = f(X) Uncertainty calculated as: |Df L | = |f(X)-f(DX L )| |Df U | = |f(X)-f(DX L )| Uncertainty propagation Tibor Kibèdi, Dep. of Nuclear Physics, Australian National UniversityNSDD 2015, IAEA, 20-24-Apr-2015 isomer  exp  j Partial  -ray half-life: X X X-DX L X-DX U f(X)
