Hello,

It seems to me that there is a bug on version 7.3.3.0 of Demetra. (Problem also found on V 7.3.0.0)

The bug occurs during the object calibration process during the step-by-step procedure.
Alpy 600 wavelength calibration is correct (see dem_1 pic)
But when you click Launch to perform the object calibration process, wrong values appear on the X axis.
See dem_2 pic (X-axis in pixels) to dem_3 pic (X-axis corresponding to ????)
Therefore, the instrumental response operation is not possible since the image is not properly calibrated in WL. (pic dem_4)

Surprisingly, the reduction process is normal if you directly click the Launch button at the bottom of the process window. All operations are performed automatically and the final spectrum is properly calibrated. Just go back to build the instrumental response «by hand».

Anybody got any ideas?

Bad use of myself. Process should be executed as follow :

1/ Object calibration >> Go
2/ Neon calibration >> Go

I was doing the opposite, which resulted wrong results.

The designers inform me that this is indeed a bug they are working on.
