sqsin(x)

sqsin(x, axis)

SQSIN is used to multiply data by the square of a trigonometric
function varying continuously from pure squared sine to pure squared
cosine. It works for 1D 2D and 3D spectra.

You have to enter first the value of the parameter x varying continuously from 0 (pure
square cosine) to 0.5 (pure square sine). x corresponds to the
position of the maximum of the filter in your window. If you are
working on a 2D or a 3D spectrum, there is another parameter which
determines on which axis (axes) the apodization will be applies.
