[Heig] HEIG Obscore Note - ready for final review/ comments on the Note #part 1

[Mireille Louys]

Hi Ian, Hi HEIG readers

Thanks for your clarifications and examples.

Still we have written the note to sort out all the differences between 
the various data sets ,
and highlighted the benefice of the statistical validation that pdf and 
draws may  bring into the game.
I find it strange to mixe them back again , as we had in the very 
beginning in Nov 2025.

The users need to segregate between the various kinds because the 3 
categories do not play the same role
in science interpretation as far as I understand.
This is also why data levels are defined f.i in CTAO.

If I want to compare pdf or draws between 2 different collections , the 
data represented need to be fully calibrated, so
they have calib_level >3 at least in Obscore sense , and can be named 
advanced data products as in Obscore 1.1

The term is not statisfying , but the distinction is , so we can keep 
this term for this note and will brainstorm later to find a better one
for the main Obscore extension WD ?

This is my suggestion.
Best wishes , Mireille
