All,
When re-examining the data and now showing also the power values above the average (graph bleu) values, then you get graph b.
Note that to the far left and far right side both graphs have the same value.
These are the silent parts; they just display the average nois; no change.
In the middle you see that the green graph is elevated, and shows peaks.
In my opinion this shows that there are peaks coming from the source.
However with our simple amateur equipment we cannot enhance them in a standard way.
I will put the raw data also on the website, so if you want, you can also struggle with it.
As a reference enter W3IRS5 in google and also in
maserdb.net Have fun with the hobby, and I hope I did not annoy you too much with my posts.
