[MSNoise] MSNoise Digest, Vol 36, Issue 9

[Thomas Lecocq]

Hi,

The autocorr being always similar could be an effect of the spectral 
whitening applied for AC like for CC. In 1.4 this was the case, and this 
means that, for AC, the phase is the same AND the amplitude is all equal 
too. This could be part of the reason your AC look like a sinc function.

You should wait for the next release to interpret AC (this new version 
will disable whitening for AC).

Best regards,

Tom

I already I 'config' the 'autocorr=Y','stack_method=linear','mov_stack=10','keep_days=Y',and etc. And  there in no error in the working process .But in the 'ccftime plot',the waveforms of every '1day-stack'is exactly same,the '10days-stack'is so on.I cannot find the reason why the autocorrelation waveforms is the same.How can i solve this problem? Many thanks.
