If there are several anisoplanatic effects present, with each not
decreasing the Strehl ratio much, it is a common practice to
multiply the Strehl ratios for the individual effects to get a
combined Strehl ratio. ...

where chromatic displacement is given in Eq. (50).
The two terms necessary for calculating the Strehl ratio are
