Variability of Hβ profiles over different years. Top: the observations have been acquired from 2005 to 2019 using different instruments: E indicates ESPaDOnS, N Narval, and H HARPSpol. Left: larger velocity range to show the full extent of the line profiles. Right: zoom-in to the line core. The profile in magenta with the strongest emission contribution refers to the HARPSpol observation in 2017 whereas the profile in navy blue colour highlights the HARPSpol observation in 2019. The middle plot shows the profiles until 2008 and the bottom plot the profiles of the later years.
