Detailed Description

A Focal-Plane.

A focal plane consists of one or more chips (according to the number of contiguous silicon). It contains pointers to the focal-plane's metadata and the exposure information. For astrometry, it contains a transformation from the focal plane to the tangent plane and the fixed pattern residuals. Since colors are involved in the transformation, it is necessary to specify the color the transformation is defined. We also include some values to characterize the quality of the transformation: the root square deviation for the x and y transformation fits, and the chi-squared for the transformation fit.
