Dear PVsyst Forum,
 
	I have encountered an issue with the Sandia IAM model implementation in PVsyst. I found the values for the six parameters of the Sandia IAM model in the help documentation and used them to calculate the IAM value. However, the result I obtained does not seem to match the expected outcome.
 
	I understand that the Sandia IAM model has been deprecated, but I am trying to compare the results from different IAM models, so I need to calculate the results using the Sandia IAM model.
 
	Could anyone explain why the calculations might not be giving the correct result? Are there any specific conditions or considerations I should be aware of when using these parameters in PVsyst?
 
	Thank you in advance for your help!
 
	Best regards, 
	Zhang Chao
