Great, I will give that a try! Thanks!

@J.M. I need the approximation to determine $l=f(\phi)$ such that I can rewrite it in a form $\phi=f(l)$. With the exact elliptic integral that doesn't seem possible.

comment Approximations of the incomplete elliptic integral of the second kind
@J.M. the use of pade approximants seems to me to be a fairly involved approach in which I have to determine all the prefactors, which I would probably need a computer for so then I don't see the point in using the approximation over the 'real' incomplete elliptic integral

comment Approximations of the incomplete elliptic integral of the second kind
I hadn't seen it yet, but after taking a look it doesn't get much clearer for me. I can see that Eq 21 in the link is an approximation, but I am not sure how I would go about applying it?

comment Detect values in array that are statistically inconsistent
That's a good point. I guess you have to know quite a bit about the physics/chemistry of what you're measuring to be able to set a sensible absolute or relative threshold.

Pretty sure that there should be, but that is a bit too tough a nut to crack for me.
