For this step in the calibration process,
you are asked to enter in either the pixel size or the detector dimensions.
The pixel size is the span of one detector pixel, in micrometers.
(The pixels are assumed to be square, which seems to be true for all currently marketed detectors).
The detector width is the width or height of the entire pixel array, in centimeters
(if the array is non-square, the larger of the two dimensions is chosen).
This is the quantity that is referred to as the "diameter" in Batch mode.
The detector diameter is the diagonal span of the pixel array,
equal to sqrt(2) times the detector width, and often quoted by detector manufacturers as the "diameter".
If you do not know these numbers it is not a problem—just leave them as they are
and the calibration wizard will still function properly.
