#include <pmFPA.h>
Collaboration diagram for pmFPA:
A focal plane consists of one or more chips (according to the number of pieces of contiguous silicon). It contains metadata containers for the concepts and analysis, a link to the parent, and pointers to the FITS header, if that corresponds to this level (the FPA may be the PHU, but will not ever contain pixels). For astrometry, it contains a transformation from the focal plane to the tangent plane and the fixed pattern residuals. It is expected that the transformation will consist of two 4D polynomials (i.e. a function of two coordinates in position, the magnitude of the object, and the color of the object) in order to correct for optical distortions and the effects of the atmosphere; hence we think that it is prudent to include a reverse transformation which will be derived from numerically inverting the forward transformation.
