Example of the Hα line profile difference of two spectra obtained at different times for star NGC2345No50 (depicted by the blue and red lines). In black are represented the two different bandpasses (Hα16 on the left and Hα06 on the right), around the Hα line centre, used to compute the Hα index for the individual spectra of the stars with ACTIN 2.
