I implemented the attached with
http://mndynamics.com/papers/bedlewo14a.pdf 3a multiplier map for hyperbolic components (page 15)
Later I will try to figure out 3b so I can also highlight the filaments that are owned by the mu-units.
Later still I'll try to use wakes to select one specific mu-unit, probably will try to highlight limbs first.
see also: https://mrob.com/pub/muency/muunit.html (but I replicated the method behind this one (afaict, something to do with mapping the multiplier to the period 1 cardioid even outside the interior of the mu-unit's owning hyperbolic component) and the distortion of features is too great - there are halos around discs where the supposed mu-unit does not align with the true #Mandelbrot set shape).
http://mndynamics.com/indexp.html Mandel by Wolf Jung can do proper renormalization
will dig into its source code (GPL) soon
https://mathr.co.uk/mandelbrot/mu-unit/#per2 got mu-unit renormalization working, the idea (reverse engineered from the code) I used from Mandel was to use 2 divided by the derivative w.r.t. z of the superstable periodic cycle (excluding the critical point z_crit = 0) as an escape radius for |f^p(z)-z_crit|.
The implementation of Mandel is a bit messy with loads of magic values (eg code does something completely different if one parameter is 65001u vs 65003u). Not many comments either.
