I looked at the docs on the official site.

The "junk" was irelevant hits ( about 20 of them to some refclock MX4200
receiver, one to ntpc, The only relevant hit was one with a "relevance
factor" or 1 star which was something like the 17th hit out of 23.
That is what I call "junk". It often happens when googling I agree.
Note I used the search on the doc.ntp.org main page, not a google search.
