A procedure will be outlined which is appropriate for threshold detector measurements that have limited uncertainty information and/or are benchmark referenced. The derivation focuses on individual detector results and the option of coarse group spectrum adjustment when observed spectral indexes are in modest disagreement with the prediction of an a priori neutron spectrum of unknown accuracy. Characteristics of the procedure include a simple choice of error components, exclusion of intrinsic spectrum interpolations, and an explicit diagnosis of the effect upon the adjustment of individual detector response parameters. A sample problem is worked out in detail.
