Small sapphire sample: Ratio between maps at NAOJ and at Hawaii

Small sapphire sample.
As I did for the LMA measurement reported in elog entry 745,
I calculated the ratio overlapping the map taken with my setup in February with the map taken by Alexandrovski.

I shifted the maps to find the minimum of the standard deviation of the ratio on the map.

The ratio is 2.55+/-0.3
