Database Window
The Database window lists all atomic and ion lines as well as molecular bands found in the database for
the given search parameters. On top the wavelength interval is given followed by the Lines found table
containing information about the lines:
Field Description
Wavelength Displays the exact wavelength of the identified line or band.
Line (nm) This is the exact wavelength of the identified line or band from the database. If
several lines or bands of the same element were found, the strongest line is
marked with an asterisk (*). Only this line is displayed in the diagram window.
Element Lists the element name and ionization state in spectroscopic notation for each
identified line or band. The color of the entry corresponds to the color of the
element in the element in the selection list of the search engine dialog box.
Line Strength: I
(rel.) Depending on your selection the line strength is displayed in relative units, in f-
values (oscillator strength) or A
ik
-values (transition probabilities).
The line strength in relative units is related to the f-value of the atomic line. A
relative line strength of 1000 corresponds to an f-value of 1. If no data is
available for an element, the relative line strengths are normalized to the
