Explanation of data folders

Great explanation. I’d love an updated explanation for DPU 1.2.1. Also, what is the unit for the photodiode for raw OD files? For example, in my vial{x}_od_raw_135.txt files, I’m getting measurements like:

0.035,679
0.0404,679
0.0459,678
0.0517,684
0.0572,681
0.0627,680
0.0681,686
0.0738,684

Is this a correct order of magnitude? Is this in mV?
