Need to re-order the corrections that are done for 2D export

Description

For 2D export, we must make sure that all appropriate corrections are done - notably the non-linear corrections (not used now), and the angle dependent transmission. Some corrections, like these, are currently only done at the average to 1D step!

The only correction that is not done at the "ADD" step is the angle dependent transmission correction, which is currently done only at the 1D averaging step. After discussion with John, it seems best to put this step at the ADD step as well. I need to work through the math as well. For the case of a (mostly) transparent EC, this is good. If the EC has a low transmission (say 70%), then there may be more of an issue.

Tentatively move the correction, document it, and make it easy to (re)move.

  • Resolution set to fixed
  • Status changed from new to closed

Moved the trans correction to the DetCorr?() function. Added globals to (0/1 off/on) the trans or efficiency corrections. Tested the change vs apoferritin, H2O, D2O, and the NIST P-cell (Tcell = 0.82, but qmax=0.16). No difference was noted between the old (1d step) location and the new 2d location.

Done.
