Gordon,

Sticking to your suggested 10-minute limit on my thoughts of items remaining to
be done before launch, here is what comes off the top of my head:

1. Internal meetings to teach each other about software. This needs
to be done with hands-on computer work (with journaling enabled).

2. De-pixelizing Forward Fitting
Part I: Code to analyticize the elementary sources -- 90% done;
Part II: the Markus-Ed interface -- TBD
Part III: testing with simulated sources -- TBD

3. Code to find the map phase center--does it exist in SSW?

4. Implementation of GH's concept in which statistics are applied to Fourier
coefficients rather than count rates.

5. Testing of near-limb imaging with the new hessi_grm.

6. Double-blind image reconstruction along the line of David Alexander's
HXT CDAW. (I'm concerned that our testing models may be too simple.)
(a) an "outsider" makes a flare model
(b) a simulated count profile is derived and given to "users"
(c) the "users" make a map and send it to the "outsider".
(d) The "outsider" evaluates the results

7. Restructuring of the count to visibility programs to
(a) incorporate a well-defined model of the "information doubling"
(amplitudes to amplitudes+phases)
(b) ensure that the output is composed of independent vectors
(like the Wavelet/Fourier transform)
(c) solve Andrew's photometry problem in polar_mem.
