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 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 = 3].
Note that it is possible to create a configuration file containing these options, along
with suitable default values. Please refer to the details provided by the 'esorex --help'
command.
