The file "scale.txt" documents the image scale for each sequence. The files "d.dat" to "j.dat" contain metadata for each run on each substrate, arranged in the following columns: 1. run number 2. frost point 3. first emergence temperature 4. saturation at first emergence 5. ramp rate (°C/min) (only runs at 0.2 °C/min were included in paper) 6. condensate visible before emergence (0=no, 1=yes) 7. both crystals emerge at once (0=no, 1=yes, 2=crystals on flat mica) 8&9. not relevant; ignore
