Okay - just to re-focus us on these lines and angles.
And to be clear, I'm going to treat the red lines as x and y axes with values
x[sub]-inf[/sub], x[sub]0[/sub] & x[sub]inf[/sub] as left, middle, right respectively, and
y[sub]-inf[/sub], y[sub]0[/sub] & y[sub]inf[/sub] as bottom, middle, top respectively
Also 'CW' is clockwise and 'CCW' is counter-clockwise.
I'm explaining that just in case it isn't obvious to everyone(!) - not trying to sound more intelligent than I really am!
Line A
Creates angles exactly 140o(CW) or 220o(CCW) from the top (x[sub]0[/sub]y[sub]inf[/sub]) of the circle, or 50o(CW) or 310o(CCW) from the right (x[sub]inf[/sub]y[sub]0[/sub]) of the circle.
Obviously there are other reference points on the circumference that we could use - but the point is the angle is a whole, round decimal in degrees if you use any of the top, left, right, bottom positions as reference points. That must be significant, right?
Slight disclaimer - when using an on-screen ruler, it gets within a tenth or fifth of a degree of the whole number. For me, that's definitely close enough given how imperfect the underlying image is.
Lines B & C
As was pointed out before - these don't (appear to!) intersect with the centre of the circle, so if there are any important angles there - then it's possibly going to be the angle they make at their intersection.
From what I can gather - the angle between them is 30o (again within a tenth/fifth of a degree)
Beyond describing an angle, I can't see what else they're for (although when you take them all the way through to the other side of the circle, they do 'frame' the little symbol in the top right quite nicely
)
It's distinctly possible that they do intersect at the line y=0 - with the low res in the spectrogram image (not the screencap, I mean the data encoded within), and with the lines starting so far from the centre of the circle, it's possible that the lines I've traced are slightly off.
Anyway - two potentially significant whole numbers there which seem, to me, to be a little bit too 'perfect' to be incidental.
What we need now are ideas for what those angles could mean, if anything.
