Hello mesa users!
This is the follow-up to this question (
I've read all of those answers from josiah and bill and could say I

But here is the question, I have *history.data* from a model that I run, I
want to gather data from timestep 1000 which is corresponding to
profile13.data (just for example), if I open the profile13.data, i have
column namely zone, LogT, logRho, logP, logR, etc which is have a 39000++
rows.What is this mean ? what is this 39000++ rows meaning for a single
timestep (timestep 1000)?

I still didn't understand this concept, because I thought timestep 1000
corresponding with one condition in stellar evolution. how could that one
condition again have 39000++ rows ? how to interpret data from files
profile13.data ?

Thank you very much for your help and I'm really sorry for this "trivial"
question, but still this is a thing that I don't understand, so still
worthy to ask.
