Why should you use fit2d?
Maud does include some utility to convert Tiff images directly. However, in the context of high pressure experiments, I prefer to perform a first processing with fit2d before starting a refinement in Maud. Why? Here is the list
- I use Fit2d anyway
- on the beamline,
- to have a first look at the data,
- to calibrate the wavelength, detector distance, detector tilt...
- and I know it well.
- Not all diffraction images are in Tiff format
- If you really want to use Maud to convert the images
- you still need to define a beam center, one way or another.
- you might not be consistent from one image to the next.
- High pressure data tend to be dirty, with a lot of background, huge stresses, and very few peaks. Therefore, I find it easier to start a Rietveld refinement if I corrected some of it already...
Now, I should point out that
- beam center, detector tilt, and detector distance from fit2d will only be used as a starting point.
- detector tilt and detector distance will be recalibrated in Maud, with the standard,
- beam center will be adjusted in Maud for each diffraction image.
