| Predominantly this is a TODO list, or a list of possible future enhancements. |
| Items labled "High Priority" effect the proper functioning of the |
| component, and should be fixed as soon as possible. Items labled "Medium |
| Priority" are desirable enhancements, often pertaining to the performance |
| of the component, but do not effect it's accuracy or functionality. Items labled |
| "Low Priority" should probably be investigated at some point. Such |
| classifications are obviously highly subjective. |
| </p> |
| <p> |
| If you don't see a component listed here, then we don't have any known issues |
| with it. |

| thereof, but they might be slower to calculate since root bracketing might |
| be needed instead of Newton iteration (for the lack of 2nd derivatives). |
| </p> |
| <p> |
| Since Boost.Math's Bessel functions are so excellent, the quick way to <code class="computeroutput"><span class="identifier">cyl_bessel_j_prime</span><span class="special">()</span></code> |

| There is a problem area at arbitrary precision when <span class="emphasis"><em>a</em></span> |
| is very close to 1. However, note that the value for <span class="emphasis"><em>T(h, 1)</em></span> |
| is well known and easy to compute, and if we replaced the <span class="emphasis"><em>a<sup>k</sup></em></span> |
| terms in series T1, T2 or T4 by <span class="emphasis"><em>(a<sup>k</sup> - 1)</em></span> then we would |
| have the difference between <span class="emphasis"><em>T(h, a)</em></span> and <span class="emphasis"><em>T(h, |
| 1)</em></span>. Unfortunately this doesn't improve the convergence of those |
| series in that area. It certainly looks as though a new series in terms of |
| <span class="emphasis"><em>(1-a)<sup>k</sup></em></span> is both possible and desirable in this area, but |
| it remains elusive at present. |
