Please show us your failed trial so we can diagnose. As mentioned in my last comment, my solution just works fine on the new vc according to my test.

@RémyGalli In a case of our Galaxy the density has a singular part $m\delta(R)$, where $m$ is the black hole mass (see Nobel prize 2020). Therefore equation for vc[R] should be update.

1. Please add the link to that "solutions given elswhere" to the body of your question. 2. My solution under your previous question fully applys to this new vc, which part are you having difficulty? (Of course you need to supplement the missing data at R==0. )

Have a look at the transformed integral equation. The expression v[R]^2/(4Pi R^2) must be finite for all values of R.

Your new dataset doesn't contain point R=0!
