# File Format

This folder contains the raw data files for the WAAM samples used in the SPIE 2023 Optics and Photonics conference paper. The raw data files are in the format `YYYYMMDD_HHMMSS_SAMPLE#_Cube.txt`. The repository also contains the background measurements for each sample, in the format `YYYYMMDD_HHMMSS_ref.txt`. The background measurements are used to remove the effects of outgassing from the chamber itself. 

# Format of raw data files

The raw data files contain the raw data from a single measurement of a WAAM sample. The measurement captures chamber pressures and temperatures over the duration of the measurement. Datetime records the date and time that each measurement of temperature and pressure is made. CH2 and CH3 record the pressures in mbar in the sample and reference chamber respectively. Temperature is measured using a thermocouple at 4 locations on each chamber (T2 - T9). One sensor also measures lab ambient temperature (T1). See the SPIE paper for more details on the experimental setup.
