  • Ticket #465 – Description

    initial v1  
    1 Megan Robertson's group from the Universtiy of Houston has indicated the need to use alternate cost functions to the current Chi^2.  This relates mostly to having features in different q ranges that are not always captured if the uncertainties vary widely between q ranges.  One should be careful in doing this of course.  On the other hand it is clear that if we are ever to have successful co-refinement of SAXS and SANS we will need to do something.  Most likely in fact weighting cost function differently for different curves?
