Example MSDP prominence profiles at the top at 16:25 UT. Intensities are in 10⁻⁶ erg s⁻¹ cm⁻² sr⁻¹ Hz⁻¹, and the unit of the x-axis is in Å. In the right corner, we see the velocity in m/s at Hα ±0.3 Å; below, the integrated intensity in erg sr⁻¹ s⁻¹ cm⁻² divided by 100 is indicated; and on the last row the FWHM in mÅ. In the left corner, the number of the pixel at the top corresponds to points B1-B11 in pixels along the vertical B line in Fig. 2 (a) and in Table 3.
