Hi,JunXian,
I also have some of 3 counts sources in my detection lists, but I do not
really trust them because using a brute force calculation of correlation
according to the wavdetect manual,
I found the detection threshold is higher, meaning these sources should
not show up in the list. I am not sure about this, but seem to me it is
caused by overestimate of background in wavdetect. I do like to hear
more about this from experts.
