<p>Hi Ian, Hi HEIG readers </p>
<p>Thanks for your clarifications and examples.</p>
<p>Still we have written the note to sort out all the differences
between the various data sets , <br>
and highlighted the benefice of the statistical validation that
pdf and draws may bring into the game. <br>
I find it strange to mixe them back again , as we had in the very
beginning in Nov 2025. <br>
<br>
The users need to segregate between the various kinds because the
3 categories do not play the same role<br>
in science interpretation as far as I understand. <br>
This is also why data levels are defined f.i in CTAO. </p>
<p>If I want to compare pdf or draws between 2 different collections
, the data represented need to be fully calibrated, so <br>
they have calib_level >3 at least in Obscore sense , and can be
named advanced data products as in Obscore 1.1 </p>
<p>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 <br>
for the main Obscore extension WD ? <br>
<br>
This is my suggestion. <br>
Best wishes , Mireille<br>
<br>

This question will need to be adressed for Obscore 1.2 ,
but for this Note we can keep "advanced data products" <br>
with the caveat that clarification is needed. </p>

<div>Shall we just drop the term altogether in the document and
just call them all “data products”?</div>
