This program is designed to match up items in two different lists, which may
|
|
have two different systems of coordinates. The program allows the two sets of
|
|
coordinates to be related by a linear, quadratic, or cubic transformation. It
|
|
is an implementation of the algorithm described in Valdes et al., Publications
|
|
of the Astronomical Society of the Pacific, vol 107, page 1119 (1995).

|
|
The program was designed and written to work on lists of stars and other
|
|
astronomical objects, but it might be applied to other types of data. In order
|
|
to match two lists of N points, the main algorithm calls for O(N^6) operations
|
|
(yes, that's N-to-the-sixth), so it's not the most efficient choice. I find
|
|
myself becoming impatient for N >= 100, but your mileage may vary. On the
|
|
other hand, it does allow for arbitrary translation, rotation, and scaling...
