Simulation HCPV,inputs data

Hello,

I am simulating HCPV with SAM.
I don't find: "optical error factor, alignment loss factor, wind flutter loss factor" in the data sheet.
Should I put them to 0 or 1 for not considering them?

For the airmass coefficients, I find only the spectral figure in function of the wavelenghts. Please, how can I have a0-a4 from this figure?

Also, I can't identify the elements from the data sheet that corresponds to the elements of " Cell Temperature".

Thanks in advance

Thanks a lot !
