It is possible to perform a dip filter with our phase-shift migration algorithm; because we calculate
with the Muir recursion (4,8), we can use the recursion
starting with *R _{0}*=

(14) |

where *r _{0}* defines the cosine of the angle that starts the Muir recurrence, often
or ; following the recursion (8) we find

(15) |

and subsequently:

(16) |

The expressions (14), (15), and (16) are the relations for a , , and dip migration in the Fourier-domain, respectively.
