Format summary

The following listing shows the required format of the parameter file. Parameters in italic are switches (0/1).


 version_number 	 The version number.

nlines The number of lines.
wavelength1 width1 [...]$^a$ The line parameters for exactly nlines lines.
...
app_s app_b, v, fixflag relative apertures for source and background, right side in
auxiliary condition (Sect. 7.1), fill empty bins with zeros
sbg sbgit bgsmooth sbgchi, n$\sigma$ sbg value, iterate and smooth switches, fit sbg with $\chi^2$, median sbg range.
dlam sigunit dsig ikev Spectral range parameters and units.
ilamit idlam iord idsig Fit $\lambda$, fit $\lambda$ with const. line distances, fit lines in higher order, fit const. FWHM
isigit Fit sigma switch.
ires Write results into file.
iformat iportrait Select file format, plot portrait switch.
iplot ilab ierrplot ilog nbin spec_only fit_only
Switches for creating plot, adding labels, plotting error bars,
plotting y-logarithmic. Bin parameter.
Switches for plotting only the spectrum/fit.
nlik ispline supported only in IDL version; (Sect. 9).
$^a$Each line may have optionally the following additional parameters/flags:

 f_N  		 	 (float) 	 weights 		 (Sect. 7.1; default: 0.0) 

flag_profileN (0/1) profile type (0 = Gauss, 1 = Lorenz, default 0)
flag_lambdaN (0/1) fit lambda (0 = FALSE, 1 = TRUE, default TRUE)
flag_sigmaN (0/1) fit sigma (0 = FALSE, 1 = TRUE, default TRUE)
flag_lockN (0/1) lock lambda (0 = FALSE, 1 = TRUE, default FALSE)
$\beta$_N (float) value for exponent applied to Lorentzian profiles
