Example MSDP prominence profiles in the main part at 16:25 UT. Intensities are in 10⁻⁶ erg s⁻¹ cm⁻² sr⁻¹ Hz⁻¹, and wavelength on the x-axis is in Å. In the right corner, the velocities in m/s at Hα ±0.3 Å are indicated; below, the integrated intensity in erg sr⁻¹ s⁻¹ cm⁻² divided by 100 is shown; and on the last row the FWHM in mÅ. In the left corner, the number of the pixel corresponds to points A1-A15 to pixels along the vertical A line in Fig. 2 (a) and in Table 3.
