Thanks for noticing this. The values are correct, the issues are in the equations. They are missing two decimal points, so for Green it should be 0.001697x – 0.0728 … The equations don’t get automatically updated using your new values, but you can update them yourself with the LINEST equation where y values = reflectance (R) values, and x values = pixel value (DN)
In the meantime, we will update the graphs and correct the equations.
You can still use the graph to check your values by manually looking at the DN and then finding the corresponding reflectance.
Hope that answers your question, and good luck with the rest of the exercise!
