[mcstas-users] [EXTERNAL] Re: SANSCurve type component for I(qx, qy) instead of I(q)?

[Wildgruber, Christoph U.]

Hi Peter,

I’ll definitely look again more carefully :-)

Besides that my strategy is to get a younger person here excited
to learn how to write a McStas component…

Thanks so much,

Uli

Hi Uli,

I might not be looking hard enough but I don’t think there is a SANS
sample component similar to SANSCurve (which uses I(q) as an input file)
that can handle I(qx, qy).

If anybody can point me in the right direction or has a component like that
to share it would be greatly appreciated!

For that sort of functionality I would be looking in the direction of the SASview (SASmodels really) sample http://www.mcstas.org/download/components/samples/SasView_model.html which does include models that are 2D in q. (It may also be that one of Henrich Frielinghaus’ contributed sample components has a similar feature?)

The limitations of the SasView_model sample are that
a) I am not entirely sure the absolute normalisation is completely correct
b) One needs to recompile when shifting between models

Should you decide to implement one yourself instead, such a model would of course always be welcome as a contribution. ;-)


Best

Peter
