SNAPPY Data:

A:  First data over Iceland right after data taking started shows all detector signals look normal.

B) and D) SNAPPY First Data inside the central core of the Electromagnetic Pole of the Earth for GAGG and Veto ADC:

Daily data sets look like this, on left one day full orbit and on the right selecting just events over the Electromagnetic poles. The GAGG detector has a 4% energy resolution so some narrow peaks are showing the improved structure.
