The 3 measurements (XY, XZ and YZ) have been finished and are reported on the attached figures.

Note that for the XZ and YZ measurements the mean and standard deviation are computed only inside the sample while the contour plot and histogram show the entire measurement.

The results is compatible with previous measurements and gives absorption ~ 60 +/- 5 ppm/cm without peculiar feature on XY plane.

I like a lot the plots in gray scale but I also did the same with colored scale.

I'll upload soon a notebook to do these plots.

The mirror is oriented to have a black dot on the top.

EDIT : changed number of bins in histogram
