Notes.
Location of the aperture center at the spectral extraction. The positions are given with respect to that of the central star in the unit of detector pixel. The numbers in parenthesis are the sizes of the apertures.
Positions and sizes of the apertures in pixel unit are converted to the physical scale assuming the distance to HD 100546 being d = 103 pc, and the pixel scale of CRIRES 86 mas.
Line center and full interval of the velocity range that the intensity of the line emission is integrated to calculate the line flux. Velocity offset is given with respect to the line center at the aperture location P4.
The measurements are from the fittings of the population diagrams with LTE models presented in the red lines in Fig. 2.
