Each folder contains one or more runs. 
Runs within each folder are usually presented as a single series of images, in which the runs follow sequentially in numerical order. Each image's filename contains a timestamp. Frost point measurements, in which the temperature is taken slowly back and forth over an equilibrium, are also contained within these folders, usually following directly on from a run. The typical sequence is "run, frost point measurement, run" with the frost point measurement applying to the run either side of it.

Files ending "temp.txt" or "temp.dat" are temperature logs. The final column is the temperature in °C; the others are the time.
