If no plot is desired, the plot procedure can be switched off by deactivating
iplot. With the switch ilab labels can be included. This will put
the numerical fit results at the proper positions in the plot, e.g., the
line fluxes on top of the corresponding line (cf. Fig. 2). With
ierrplot error bars
are plotted with the spectrum. Logarithmic plotting is provided with
ilog=1 scaling the y axis logarithmic. Finally the data can be binned with
nbin. The bin-size in Å can be deduced from the y-label. If the user
wishes to plot only the spectrum without any model,
the parameter spec_only can be used. The fit procedure, labeling etc.
will then be switched off and only the spectrum, binned with nbin,
with title fittitle etc. will be created.
Otherwise only the fitted curve can be plotted by suppressing the plot of the spectrum ( fit_only=1).
Two more parameters are provided in the parameter file, but are only supported in the IDL version (cf. Sect. 9).
In Fig. 2 a PS file, created with the plot routine, is shown, using the parameter setting shown in Fig. 3. The fit was constrained, as described in Sect. 7.1, granting a certain line ratio to be kept, such that reasonable temperatures are consistent with the fit result. In this way a de-blending was attempted.
