Hi Edward.

I actually think it is a quite elegant solution, that if one does not
load R1 data, then the R1 parameter is fitted.

I think it is a better solution than the previous suggestion.

It involves less coding, and the logic is sound.

And the system is still "open" for weird stuff, whereby you by
scripting can analyse with and without fitting R1 in same analyses.

I think this is best.

But in the end. Potato, tomato.
If this solution prevents any further implementation, then this could
also be done.
