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

Hi,
You are using the master version or release 1.4?

http://mailman-as.oma.be/mailman/listinfo/msnoise Hi,Thomas
I'm Sun Jie . 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.
