Determine the spherical-harmonic bandwidth that is necessary to achieve a certain concentration factor.
lwin = SHFindLWin (
- The spherical harmonic bandwidth
- The angular radius of the spherical cap in radians.
- The angular order of the taper.
- The desired concentration factor of the window. This must lie between 0 and 1.
taper_number: optional, integer, default = 1
- The taper number corresponding to the angular order
m. The default is to use the first taper.
SHFindLWin will determine the spherical harmonic bandwidth that is required for a window of the spherical-cap concentration problem to achive a certain concentration factor. By default, the first taper corresponding to the angular order
m will be used, but this can be modified by specifying the optional argument
