XY Surface Absorption Maps and some statistics of GT ETMX

Simon

Please find attached the absorption maps of GT's ETMX mirror substrate that is currently being analyzed in the absorption bench.
For now, we have three XY maps taken at different positions along the c-axis (Z = 46, 79, 112, where "79" marks the center of the mirror related to the bench-alignment; given in [mm]).

I also calculated some histograms which give statistics on the distribution of the absorption-values.
