Where does this graph on the Mk 47 motor for the AIM-54 come from & where is the report being mentioned by David Bowie

I was looking into what the actual thrust of the AIM-54 should be, & I found 4000 lbs for 30 seconds in a 1984 weapons file, with a 1977 thesis giving the same number as an average thrust. I will link both below, however I noticed a rebuttal to the 1984 report by one David Bowie, who cited burnout test data for the AIm-54 Phoenix motors but did not provide a link, citation, or screenshot of those tests. I also found the particular graph below attached as an official rebuttal to a bug report regarding AIM-54 thrust, with no link or citation. Can anyone identify where these were sourced from?

If I remember correctly, the report by David Bowie was a god-awful small affair.

What do you mean? I not trying to blow things out of proportion if that’s what you’re saying, I just want to figure out where it came from.
