      Description

      To help us evaluate WCS options, we need to create a relatively complicated composite model in AST and GWCS, using a few models currently available within the existing packages. A minimal composite model to test these things would include:

      • FITS linear transform
      • ccd distortion
      • optical model
      • FITS TAN WCS

      The middle steps do not need to be realistic models, just something that we can use to compare AST's and GWCS's respective interfaces and capabilities for creating the composite model, and test for differences in their results. We can then use this model to evaluate performance when run on different numbers of pixels.
