Barplot of the Q_f values of the images of the Hα-0.2 Å dataseries. The horizontal dashed blue line corresponds to images with a ratio of Q_f = 1, namely, images with the mean quality. Images with Q_f less than 0.4 were considered as highly blurred and were removed. This threshold is marked by the horizontal light green line. The gaps in the plot correspond to a total number of 21 removed images from the initial pipeline (16 images) and the application of the above threshold (five more images).
