Dear François,
But when integrating over large solid angles, the exact geometry of the experimental setup plays a crucial role in determining the selfabsorption correction and I doubt that a useful implementation into iFeffit would be possible.
yes but if you say so nothing will ever work. one has to start. I would be amazed to see that one day, the perfect self absorption correction code will work.
Maybe the point I wanted to make here wasn't clear enough. When you start integrating for a large solid angle detector you have to take into account the distance from the beamspot on the sample to the detector, vertical and horizontal projection of the position of the beamspot on the detector, the shape and size of the detector, cutoff angles, ... I didn't want to say this is impossible or won't work (it does). I'm just not sure how the realization of this complex task could look like, so that the number of satisfied iFeffit users will justify the time Matt spends on writing the code. Of course you have to start somewhere go get something to work. But this is where I would NOT start. An easy to use small solid angle version with only a couple of unambiguous parameters seems a much more favorable starting point to me.
