pybsm.otf.functional.slice_otf

pybsm.otf.functional.slice_otf(*, otf: ndarray, ang: float) → ndarray

Returns a one dimensional slice of a 2D OTF (or MTF) along the direction specified by the input angle.

Parameters:

• otf – OTF defined by spatial frequencies (u,v) (unitless)

• ang – slice angle (radians); a 0 radian slice is along the u axis. The angle rotates counterclockwise. Angle pi/2 is along the v axis.

Returns:

o_slice:

one-dimensional OTF in the direction of angle; the sample spacing of o_slice is the same as the original otf
