startup recipe (large ranges for parameters affecting single ph exposures, dist
coeff fixed). 2 - Like 1, but includes parameters affecting all ph positions. 3 -
Scenario for use in fine tuning cfg to match routine single pinhole exposures. All
parameters affecting 1ph exposures except dist coeffs are included and parameter
