The optical emission spectra consist of 5 collumns conaining the region of interest (ROI) , the frame, row, column and intensity.

ROI		the region of interest is the area on the ICCD detector chip on which the spectrum is measured.
Frame		for time resolved measurements, the frame indicates the time window in which the spectrum is integrated. Here, only cw-spectra were measured, so the frame is always 1.
Row		ICCD detector pixel y-position relative to the ROI. Here, Row is always 0, since the rows of the ROI have been integrated to get a 2D spectrum.
Column		ICCD detector pixel x-position relative to the ROI. Essentially the wavelength position that can be transferred into nanometers using the wavelength calibration: wavelength/nm = 2.78215E-02*pixel + 8.14694E+02 with R² = 9.99986E-01.
Intensity	the measured intensity
