![]() The sine taper also has two specific parameters In the case of the sine taper, parameter nw is useless, and both FtestĪnd jackknife are forced to FALSE. Indicates the total length of the data after padding.Ĭhoose between dpss-based multitaper (the default,'dpss') or sine taper This function pads the data before computing the fft.
