4.4 Passband Data and Calculated Responses

This section provides a summary of the expected passbands of the M F, M' F' and CD channels based on vertical incidence, nominal opening angles, electronic noise, and detector thickness variations. It uses lab-measured electronic thresholds and thicknesses. The calculations were done with PAMY (Armstrong, 1972).

HISCALE CHANNEL LOGIC ( R. Gold in consultation with S. Gary)
Z2 = D2 x (C1) x (B3)
Z2a = D2a x (B3)
Z3 = D3 x (C1) x (B3)
Z4 = D4
