pk_parabola

peaklets.pk_parabola(Nt)

* DEPRECATED: SCALE 1 IS ALWAYS EMPTY BECAUSE IT FALLS BETWEEN ADJACENT INTEGER WIDTHS. *

Convex parabolic peaklets. The scale is FWHM of the parabola,

which is the distance between roots divided by np.sqrt(2).

Input:

Nt, the length of the time series to be transformed.

Output:

sc, a 1D numpy integer array of scales. pk, a list of 1D numpy float arrays, containing the peaklet

functions associated with each element of sc. Note that len(pk[i]) = 1+sc[i].
