Description (last modified by butler)

Megan Robertson's group from the Universtiy of Houston has indicated the need to use alternate cost functions to the current Chi2. 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?
