Normalisation of USANS data in reduction

Reported by: ajj Owned by: ajj
Priority: major Milestone: USANS Reduction Wish List
Component: USANS Reduction Keywords:
Cc: Blocking:


Use of counting prefactor in experiment showed up problem whereby transmission calculations
use count time without accounting for prefactor, rather than monitor counts for normalisation.

This causes problems when people use prefactors and when the beam is not steady.

Please fix this.

  • Status changed from new to assigned

Replying to ajj:

Prefactor accounting has been added and checked in revision [51].

Root and branch reform to use monitor count normalisation still required.

Fixed. Monitor normalization was being used but the code was somewhat obfuscated.
