Low energy photons
Notes:
- perform following runs after tagger has been moved and recalibrated to catch low energy photons (500mev beam and maximum bending power)
- required statistics is based on previous tagger setup, evaluate feasibility after some runs and maybe reduce statistics to the benefit of configurations
- trigger for tagged photons is S0&S2&S4&C1&C2&NoS3
- trigger on S0 should be 5K/spill
