f(x)=sqrt((ax)^2+r^2)+kx-f_corr
f(z)=sqrt((a*(z-z_corr)^2+r^2)+k*(z-z_corr)-f_corr
f'(x)=0 -> x=sqrt(1/r^2-a^2)
z_corr=(kx*rc/a)/*sqrt(a^2-kx^2)
f_corr=sqrt((a*(z-z_corr)^2+r^2)+k*(z-z_corr) - sqrt((a*(z)^2+r^2)

k=a*func(tilt]), func(-inf)=-1, func(0)=0, func(+inf)=1
k=2/pi*atan(tilt);
d_k/d_tilt = 2/pi*(1/tilt^2)
x=z_in-(z0+z_corr)
Ideally I should match second derivative near minimum to isolate tilt from ar[3] - adjust r_eff and then shift
Maybe not, just keep iot as it is (matching f" at minimum while tilting will cause a sharp turn nearby)
