#878 new defect

broad q resolution for USANS and negative q for USANS

Reported by: pkienzle Owned by:
Priority: major Milestone: SasView 4.3.0
Component: SasView Keywords:
Cc: Work Package: SasView Bug Fixing

Description

The slit resolution function in sasmodels/resolution.py assumes that q_x>0 and that delta q_x << q_x. However, with wide open slits at low q it is possible that the resolution calculation should include theory values from q_x < 0.

Part of the solution will be to change the extrapolation function which picks the q points for low q values as indicated in ticket #835 comments. The other part will be updating the slit_resolution function to handle negative q values correctly.
