- | - Calibrate your experiment. This should be done with either Dioptas or Fit2D. Beam centers and detector distances you find in Dioptas or Fit2D will be used at a later stage of the processing. | + | - Calibrate your experiment. This should be done with either [[software:dioptas|Dioptas]] or [[software:fit2d|Fit2D]]. Beam centers and detector distances you find in Dioptas or Fit2D will be used at a later stage of the processing. |

- We often also calibrate [[software:Maud|Maud]] as this point. We will use it later to figure out the cell parameters of our sample. As you start using MAUD keep a note of the parameters you use to convert your tiff images into ESG. You will need to use exactly the same ones on your sample images later. | - We often also calibrate [[software:Maud|Maud]] as this point.
