Table 3 Data reduction modes of the MEP-i

From: Medium-energy particle experiments–ion mass analyzer (MEP-i) onboard ERG (Arase)

Mode Notes
Raw No reduction
Superposition N-spin accumulated where \(N = 2^{i} \left( {i = 1, 2, 3} \right)\) and i can be determined by commands
Snapshot Non-reduced full spin data are obtained once per N spins, while the other \(\left( {N - 1} \right)\)-spin data are discarded where \(N = 2^{i} \left( {i = 1, 2, 3} \right)\) and i can be determined by commands
Spin-phase mask Only 1-spin-phase data are derived from N-spin-phase data, where \(N = 2^{i} \left( {i = 1, 2, 3} \right)\) and i can be determined by commands
