Weibull distribution coefficients for accuracy?

The accuracy study you guys did was great (https://www.ardusimple.com/testing-simplertk2b-accuracy-in-rtk-base-rover-configuration/)!  Is it possible to get the Weibull fit coefficients for the data? I was building a system accuracy model and wanted to use the Weibull distribution to model the GPS accuracy.
Thank you!

Hi arsenix,
For our data, we came out with the following parameters:
k = 1.09
λ = 6.1e-3
Some user suggested that the data should fit a chi-squared pdf, we tried and the match is similar to the Weibull pdf https://www.ardusimple.com/wp-content/uploads/2018/11/weibull-chi-squared.png
