Dear Tyler,

I would like to attend the meeting but at 10 am I have another meeting.
Would it be possible to move the meeting at 11:00 am?

thanks
patrizia

The resulting plot (2017-11-25_1400_to 1800.jpeg) is attached. From the data, the largest difference is 1.22% and the average difference is 0.75% +/- 0.22%. This is within the specs of the sensor.
