MLX90614 temperature values of IR1 and IR2？？ #2

Hi

I found MLX90614 to be perfectly supported on Linux, which saved me a lot of time. But I have some questions in the use process, please give me your advice.

MLX90614 has two IR sensors. After I get two temperature values respectively, I find that IR1(0x07) is closer to the real temperature, and IR2(0x08) often has larger deviation. So, how do I use these two temperature values? Is it just the temperature of IR1, or two to average? The data book does not state clear.

One is Ambient and the other is the Object the device has in its FOV.
