Due to limited accuracy in the Saturnian satellite ephemerides, Cassini can be
sometimes observed to crash into a moon instead of performing a close flyby,
e.g. the Aug. 11, 2008 flyby of Encela…

chebpoly Chebyshev polynomial.
F = chebpoly(N) returns the CHEBFUN corresponding to the Chebyshev
polynomials T_N(x) on [-1,1], where N may be a vector of nonnegative

Would you consider a PR for a gamma function implementation? I have a Decimal.js gamma function implemented using the Lanczos approximation.

Should Hermite polynomials be in this package? Banded derivatives don't change the basis and Multiplication can be done by recurrence. There could also be a parameterized HermiteWeight with a Gaussian…

It seems that Chebyshev polynomials `T_k(x)` are not orthogonal in Chebfun.
```
x = chebfun( 'x' );
for k = 1:1000
v(k+1)=sum( chebpoly(k)./ sqrt(1-x.^2) );
end
plot(v)
```

The tests should be distributed near the code which they test - maybe …

Does skyfield provide position data for non-Terran satellites, in particular the 4 large Jovian satellites, Titan, and other non-Terran satellites "easily" visible from Earth?

I'm not even sure this is possible, but it would in principle allow for
``` julia
typealias Chebyshev{2} Ultraspherical{1}
```
and then the third and fourth kind polynomials could be `Chebyshev{3}` …

I can think of some ways to use this in 2D. For instance, all the transform! routines in the TensorSpace.jl file could be planned, since they're all the same size. Also, it might be useful for the low…
