DeltaGain: Gain value to seed the positioning error correction. Generally a value of 1 to 1.1 will work. e.g. A desired position of 1000cts with error correction of 100cts and gain of 1.5 will result in a new position to be equal to 1000cts + (100*1.5)cts = 1150cts

No
Crystal: Select the crystal type for the energy move. 0 -> CrystalSi111 1 -> CrystalSi311
