log : bool
Flag specifying if the spectral binning is performed on logarithmic
scale or not; if set, the number of used bins is set
automatically (if not given otherwise); by default no binning
is done (default: None).
nbin : integer
Number of used spectral bins; if given `log` is set to ``False``;
integers below the minimum of 3 induce an automatic setting;
by default no binning is done (default: None).
binbounds : {list, array}
User specific inner boundaries of the bins, which are preferred
over the above parameters; by default no binning is done
(default: None).
vmin : scalar
Sets the lower limit for the uniform distribution.
