CCS/BQ40Z60: How to choose NTC in Bq40z60

Hi TI:

     1, Based on your description, my current thermal coef is default coef, and my current NTC and second source NTC are both 10K NTC. That means I can use these two NTCs in my current FW. Right?

      2, If I use default thermal coef, there are different 10K NTCs in market. Even if R tolerance and B tolerance are same, there is some difference among R/T table. How can I choose one to make temperature reading in FG(use NTC and default coef) more accuracy? I just want to know the criteria how to choose NTC.

Thanks!
