In the equation describing how to decode the raw data from the sensor

The line that reads: Vos = -2.9power-5 - 5.7power-7 (tdie2 - 298.15) + (tdie2 - 298.15)power2 Should read: Vos = -2.9power-5 - 5.7power-7 (tdie2 - 298.15) + 4.63power-9(tdie2 - 298.15)power2 There is a missing multiplication by 4.63power-9 which caused an incorrect result. The shortcomings of entering text into a web browser mean the I have represented a superscript type with the word "power". I discovered this by comparing the results computed by the example equation in the book with those computed by the example source code from the manufacturers.

Note from the Author or Editor:
Thanks for pointing that out. You are correct, of course. For those reading this, the error is in the printed equation. The code right below the equation is correct, and includes the 4.63e-9 term.

3rd paragraph

The sentence "Here we do the same thing for the y- and x-axes..." should be "... the y- and z- axes..."??

Note from the Author or Editor:
You are correct. The third paragraph currently reads: "Here we do the same thing for the y- and x-axes, coloring the plots red and blue." It should read: "Here we do the same thing for the y- and z-axes, coloring the plots red and blue."
