Network Study - Intensities and their Distribution
The following images illustrate the hypothesis that the intensities
of lines and continuum considered in this study all follow a lognormal
distribution, and that the width of this distribution depends on their
resp. formation temperature. For each case, a Gauss-fit and its estimated
standard deviation are stated. Portions of the curve that were considered
"relevant" for the fit (i.e. to avoid line blends or other disturbing effects)
are marked with boxes. Intensities are generally in counts per line, for
continuum they are in counts per Angstroem.
As a concluding
graph, temperature vs. lognormal width is given for this and a few other
studies' preliminary results. It appears that transition region lines around
80 000 - 100 000 K produce the widest variety of intensities.
