June 15, 2023: First test flight

The top two plots below are maps showing the flight pattern over California. The line changing color is the ground track of the plane and the changing color is a function of time. The aircraft flies northward (there are small arrows indicating direction).

The middle and bottom plots show the counts in the BGO+LYSO instrument and the altitude for the whole duration of the flight. The x-axis is the time (total duration of about 3 hours 30 min). The count rates follow what is expected: reduction when leaving ground because the aircraft moves away from natural ground-level radioactivity, then there is sharp increase due to cosmic ray radiation when the aircraft reaches higher altitudes.
