The Median Filter Gradient Similarity (MFGS, Deng el al. 2015) is closely related to the seeing conditions under which the data are taken. The red bullets represent the mean value of the MFGS during the image sequence, whereas the blue vertical bars indicate the range between minimum and maximum MFGS values.
