Following the proposal and discussions at the most recent code team telecon (http://great3.pbworks.com/w/page/53909595/Code%20team%20telecon%2022%20May%202012), the third GalSim general milestone will be focused on consolidating the great progress made so far.

The primary items to be tackled for this milestone are:

1. Finishing the work to make shear conventions consistent (Issue #134).

2. Finishing the work to make radii/size specifications consistent for all objects where possible, and to provide conversion facilities where possible (Issue #142).

3. Finalizing plans to make the SBProfile class immutable, including ensuring that any issues associated with future parallelization are considered, and/or used shared_ptr functionality (Issue #107).

4. Set up a timing / profiling system to allow optimization now that we can make large jobs with multiple object input (Issue #89) [UPDATE: After major speedups and timing by Mike, this is being deferred but the issue left open]

5. Test and refine the new photon-shooting capabilities added by Gary in the last weeks (Issue #163).

6. Finish the OpticalPSF / optics module by cleaning up internal notation and adding pupil obstructions such as a secondary mirror and perhaps struts (Issues #35, #166).

7. Making the input config system more restricted / tailor-made to our specific requirements (Issue #148).

8. Begin fact-finding about possibilities for a stochastic turbulent model of the atmospheric PSF (Issue #169).

As usual, we'd like to have some demo scripts associated with this milestone (#175).

Deadline: 3 weeks (+1 one working day, plus an additional week extension, to finish on Friday 22 June 2012)
