Evolution of the average density in 10⁹ cm⁻³ (first panel), average temperature in MK (second panel), average synthetic 171 Å and 304 Å intensities in DN s⁻¹ (third panel), and the relevant energy fluxes from the energy equation (fourth panel). All quantities are averaged within a region around the prominence indicated in Fig. 8. In the fourth panel we display the absolute value of radiative cooling. The data include averaged values before, during, and after the evaporation.
