Subject:Reaction product (SF4) field for quantities at resonance

In EXFOR, we have following rules about resonance parameters:
1) Resonance parameters are flagged with a "." in dictionary 236;
2) There is no reaction product (SF4) given if the reaction specifies a resonanceparameter;
3) For resonance parameters, resonance energy is specified. It is coded either under
the data heading EN-RES, or, if coded under REACTION (specified by the code EN
given in REACTION SF6), under the heading DATA.
All resonance parameters defined in dictionary 236 by resonance flag “.” aresummarized in next page. Some codes (e.g. cross section at resonance) are for“quantities given at resonances” rather than “resonance parameters”, and it would be
useful to give reaction product in SF4 for such quantities. Therefore we propose
1) to change reaction type of cross section and partial cross section at resonance fromRP and RPP to CSR (cross section at resonance) and CRP (partial cross section atresonance), respectively.
2) to remove resonance flags of quantity codes which reaction types are other than RP,RPP, RE or RPE.
