Wavelet transformation of a time series includes padding with zeros at the edges. This function determines the spectrum borders influenced by edge effects.

This code has been developed by Huidong Tian (archived R package `WaveletCo`

).

1 |

`start` |
starting value (in time units) at the time axis |

`dt` |
time resolution, i.e. sampling resolution on time domain |

`nc` |
number of columns/time steps |

`nr` |
number of rows/scales |

`Period` |
the Fourier periods (in time units) |

a list with the following elements:

x, y | : | coordinates of the cone of influence | |

axis.1, axis.2 | : | the axes for plotting purpose |
