RIX Lars : MET-2161 Critical Algorithm 10.9 IFU image and cube reconstruction needs more work

[astronomyk]

https://jira.eso.org/browse/MET-2161

As part of its FDR deliverables the consortium has delivered a framework with prototypes of four critical algorithms. While the overall framework and three prototypes could be reviewed, the "IFU image and cube reconstruction" prototype could not.
The necessary run-time environment for this prototype to run could not be established within a reasonable time frame. A review of the prototype source code suggests that some work is still needed.

@sesquideus what was the TLDR of your chat with Lars?

@astronomyk I think the TLDR would be what is written in the RIX. I still see three options, and personally prefer the third

• submit Oliver's matrix formulation with double interpolation and then change it if necessary,
• let me write a wrapper that would show the capabilities of the algorithm for a very small image (order of 10×10).
• discuss the pros/cons of pixel tables with MUSE at FDR and then promise to implement whatever comes out as better.
  In the meantime I will make sure to read the MIRI + MUSE papers thoroughly.
