Coma reminds of itself in a very insignificant manner. The image of a circular diode in the centre is circular. It is deformed in an insignificant way at the corner of the frame.
Astigmatism behaves similarly to coma. It is not at the 0 level nor insignificant, but reaching the 5.7% level it deteriorates the image only in a small degree.
