About the mincaps/maxcaps:
These have a center and radius-squared, describing the region
inside a small circle on the sphere.
The "mincaps" describe the regions that are definitely owned by a
single healpix -- ie, more than MARGIN distance from any edge.
That is, the mincap is the small circle centered at (0.5, 0.5) in
the healpix and with radius = the distance to the closest healpix
boundary, MINUS the margin distance.
Below, we first check whether a new star is within the "mincap"
of any healpix. If so, we stick it in that healpix and continue.
Otherwise, we check all the "maxcaps" -- these are the healpixes
it could *possibly* be in. We then refine with
healpix_within_range_of_xyz. The maxcap distance is the distance
to the furthest boundary point, PLUS the margin distance.

* We use a clever trick to estimate CD, A, and B terms in two

*
* Rearranging the SIP equations (see sip.h) we get the following
* matrix operation to compute x and y in world intermediate
* coordinates, which is convienently written in a way which allows
* least squares estimation of CD and terms related to A and B.
*
* First use the x's to find the first set of parametetrs
*
* +--------------------- Intermediate world coordinates in DEGREES
* | +--------- Pixel coordinates u and v in PIXELS
* | | +--- Polynomial u,v terms in powers of PIXELS
* v v v
* ( x1 ) ( 1 u1 v1 p1 ) (sx )
* ( x2 ) = ( 1 u2 v2 p2 ) * (cd11 ) :
* ( x3 ) ( 1 u3 v3 p3 ) (cd12 ) :
* ( ...) ( ... ) (cd11*A + cd12*B ) :
* cd11 is a scalar, degrees per pixel
* cd12 is a scalar, degrees per pixel
* cd11*A and cs12*B are mixture of SIP terms (A,B) and CD matrix
* (cd11,cd12)
*
* Then find cd21 and cd22 with the y's
*
* ( y1 ) ( 1 u1 v1 p1 ) (sy )
* ( y2 ) = ( 1 u2 v2 p2 ) * (cd21 ) :
* ( y3 ) ( 1 u3 v3 p3 ) (cd22 ) :
* ( ...) ( ... ) (cd21*A + cd22*B ) : (Y4)
* y2: scalar, degrees per pixel
* y3: scalar, degrees per pixel
* Y4: mixture of SIP terms (A,B) and CD matrix (cd21,cd22)
*
* These are both standard least squares problems which we solve with
* QR decomposition, ie
* min_{cd,A,B} || x - [1,u,v,p]*[s;cd;cdA+cdB]||^2 with
* x reference, cd,A,B unrolled parameters.
*
* We get back (for x) a vector of optimal
* [sx;cd11;cd12; cd11*A + cd12*B]
* Now we can pull out sx, cd11 and cd12 from the beginning of this vector,
* and call the rest of the vector [cd11*A] + [cd12*B];
* similarly for the y fit, we get back a vector of optimal
* [sy;cd21;cd22; cd21*A + cd22*B]
* once we have all those we can figure out A and B as follows
* -1
* A' = [cd11 cd12] * [cd11*A' + cd12*B']
* B' [cd21 cd22] [cd21*A' + cd22*B']
*
* which recovers the A and B's.
*

/*
* Dustin's interpretation of the above:

* min || b[M-by-1] - A[M-by-N] x[N-by-1] ||_2

* N = the number of SIP terms.

* mA = [ 1 u_2 v_2 u_2^2 u_2 v_2 v_2^2 ... ]
* [ ...... ]
*
* Where (u_i, v_i) are *undistorted* pixel positions minus CRPIX.

* The answers we want are:

* [ sx ]
* x1 = [ cd11 ]
* [ cd12 ]
* [ (A) (B) ]
* [ cd11*(A) + cd12*(B) ]
