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 wavecal
exposures. All parameters affecting 1ph exposures except dist coeffs are included and
parameter ranges are small. (For use by flexcomp in 1ph case). 4 - Like 3 but includes parameters
affecting all ph positions (Standard for use by flexcomp in 9ph case and 2dmap). 5 - Like 4
but includes also dist coeffs 6 - Just dist coeffs (and chipx, chipy) (long; default: 3). The full
name of this option for the EsoRex configuration file is xsh.xsh_flexcomp.model-scenario [default
