GetFitVal

class zgoubidoo.commands.commands.GetFitVal(label1: str = '', label2: str = '', *params, **kwargs)

Bases: zgoubidoo.commands.commands.Command

Get values of variables as saved from former FIT[2] run.

This keyword allows reading, from a file whose name needs be specified, parameter values to be assigned to optical elements in zgoubi.dat. That file is expected to contain a copy-paste of the data under the FIT[2] procedure as displayed in zgoubi.res, normally under the form.

A ’#’ at the beginning of a line means it is commented, thus it will not be taken into account. However a copy-paste from zgoubi.res (which is the case in the present example) would not not need any commenting. Since some of the FIT[2] variables may belong in [MC]OBJET, GETFITVAL may appear right before [MC]OBJET in zgoubi.dat, to allow for its updating.
