Note: Ratio is computed as (Sector 7 - Sector 8)/(Sector C - Sector 8) where Sector 8 is shield-penetrating background, Sector 7 is the full intensity for an "open" sector and Sector C is the "Chicken" sector in which the LECP was moved through two 1.8 degree steps from the background or shielded position towards the open, or normal position. 45 degrees of rotation, or 25 1.8 degree steps are required for full sector movement.
