We want to have code able to generate postage stamp images consisting of

i) a simple parametric galaxy model

ii) ...convolved with a simple atmospheric PSF (e.g. a Gaussian, or Kolmogorov)

iii) ...convolved with a simple telescope optical PSF

iv) ...pixelated with additive Gaussian / Poisson noise

Convolution will be performed via DFT for this first General Milestone. The code at this stage will be fully deterministic, i.e. we are drawing galaxies and PSFs with specific properties (either the default or user-specified) rather than making sets of galaxies with parameters that are drawn from specified distribution functions.

Primary involvement (& issues):

Python layer gluing everything together (=Jim's existing issue #12, new issue #59 about base classes);
creation of a new atmosphere module (=new issue #25);
merging in the optical PSF module (=completed issue #13) and updating (#33);
creation of the simple noise module (=new issue #26);
random number generation (=new issues #30, #31, #32)

Additional support will be needed related to:

unit testing and documentation of new capabilities (=not a separate issue - should be part of the writing and testing of these new modules);
demo scripts to showcase these new capabilities (=new issue #27).

Deadline: 3 weeks (+1 one working day to finish on Friday 6 April 2012)
