Output files from IOSystem.calc_all()

[flyingelephante]

Hi, I'm still new in using the pymrio package, so I have three questions:

a) Using the Eora26 as my database, when I use IOSystem.calc_all(), I get two folders: Q and VA (Value Added). Both of them contain files with the same name but different values. Example, F, S, D_cba, D_pba etc.

Looking at the content of these folders, Q represents the satellite accounts (energy use, emissions and others) and VA is the value added (compensations, taxes etc.). But when I tried to do pymrio.calc_S(F, x), does this 'F' represents the factor production in the satellite folder?

If so, where does the 'F' in the VA folder contribute to?

b) In the terminology section, F (factor production) represents extensions plus value added block. So, if I refer to question (a), does that mean the 'F' for value added block already considered in pymrio.calc_S(F, x)?

c) The value added block, is this the same as the 'value added matrix' that we sum with the transaction matrix (Z) to get the total industry input matrix? Or does it represent something completely different?

Thank you!
