OPTIONS

--stack_method <str>
Frames combination method (str; default: 'median'). The full name of this option for the EsoRex configuration file is fors.fors_dark.stack_method [default = median].
--minrejection <long>
Number of lowest values to be rejected (long; default: 1). The full name of this option for the EsoRex configuration file is fors.fors_dark.minrejection [default = 1].
--maxrejection <long>
Number of highest values to be rejected (long; default: 1). The full name of this option for the EsoRex configuration file is fors.fors_dark.maxrejection [default = 1].
--klow <float>
Low threshold in ksigma method (float; default: 3.0). The full name of this option for the EsoRex configuration file is fors.fors_dark.klow [default = 3.0].
--khigh <float>
High threshold in ksigma method (float; default: 3.0). The full name of this option for the EsoRex configuration file is fors.fors_dark.khigh [default = 3.0].
--kiter <long>
Max number of iterations in ksigma method (long; default: 999). The full name of this option for the EsoRex configuration file is fors.fors_dark.kiter [default = 999].

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.
