add HU->mu slope conversion capability for more than 2 slopes
@KrisThielemans there are some in Duetto/PetToolbox, you mean those, or some others?
yes, the ones in the pettoolbox. 3 pieces I believe, but I don't think the 3rd matters in practice (without contrast)
@KrisThielemans can I just take them from there and add them myself? Or is it private info?
according to the letter signed by GE, we can incorporate knowledge from the pettoolbox, so this should be alright.
This is the non-contrast part of the info in there. I can find some time to add this to the json.

Seems that for now, STIR only accepts 2 slopes and 1 breakpoint. What do we do about this?
https://github.com/UCL/STIR/blob/master/src/buildblock/HUToMuImageProcessor.cxx#L171
Yes. Let's just take the first 2 pieces for now
Please put it on release4
This has been done now. I'll leave the issue open (but reassign) for later to add more then 2 slopes.
