• Call: import fullseye as fs; fs.ledger.dual_kvp_channels(spectrum_low, spectrum_high, detector: 'str' = 'CSI', detector_mm: 'float' = 0.6) -> 'dict' (to call the implementation directly, import dualxray; dualxray.dual_kvp_channels(spectrum_low, spectrum_high, detector: 'str' = 'CSI', detector_mm: 'float' = 0.6) -> 'dict'; from the registry, opstomography.get("dual_kvp_channels"))
The two channels of an energy-integrating (scintillator) detector imaged at two tube voltages.

信号は吸収した光子のエネルギーの和(gain = E)。分散は Σ φ E² e^{−μt}(複合 Poisson、Swank の雑音の増えは入れない)。2 つのスペクトルは同じエネルギーの格子に載せる(線形補間、範囲の外は 0)。返り値の形は photon_counting_channels と同じ(mode = "integrating")。
