[nenes82]

HEllo,

first, thanks for your job.
I have a problem with the data like left_power_phase, avg_left_power_phase. Your script return NaN or nulll.
With an other script in python I get this data: (347.3437554272462, 201.0937531420899, 212.34375331787115, 94.218751472168). Data type is uint8
I didn't succeed to understand how this script work for bugfixes that. If you have an explanation ....

Regards
