Detailed Description

Chip data structure.

A chip consists of one or more cells (according to the number of amplifiers on the device). The chip contains metadata containers for the concepts and analysis, a link to the parent, and pointers to the pointers to the various FITS data, if that corresponds to this level. For astrometry, in addition to the rough positioning information, it contains a coordinate transform from the chip to the focal plane. It is expected that this transform will consist of two second-order 2D polynomials; hence we think that it is prudent to include a reverse transformation which will be derived from numerically inverting the forward transformation. A boolean indicates whether the chip is of interest, allowing it to be excluded from analysis.
