permissible range for slope error values for CPC

[AditiiiGarg]

I am simulating a CPC model in tonatiuh. I want to add values for optical errors such as slope error and specular error. I understand they need to be entered in specular rough standard material. I would like to know what is the range for these values permissible in tonatiuh. Is there any document or text which I could refer for CPC.

I have gone through this document 8.4.3 The Contribution of Errors (http://www.powerfromthesun.net/Book/chapter08/chapter08.html). However, as per the text they are applicable for parabolic troughs and dishes.

Hi, The slope and specular error must be defined in mrad. Define them as a positive real number for the simulations and there is not limit value.

thank you amutuberria
