All files are in TAB-delimited .txt format
----------------------------------------------------------------------
Surface plot data

acid_soap...SAXS_surfaceplot_Xmin.txt - rows = scan position; columns = q value positions; numbers are scattering intensities
qvalues_surfaceplots.txt - qvalues for each column in the surfaceplot file


----------------------------------------------------------------------
SAXS/WAXS patterns during humidification/dehumidification (particle centre)

acid_soap...SAXS_particlecentre.txt - rows = q value positions; columns = scan number (time); numbers are scattering intensities
acid_soap...WAXS_particlecentre.txt - analogous to SAXS data
SAXS_qvalues.txt - q values to use for SAXS data
WAXS_qvalues.txt - q values to use for WAXS data

----------------------------------------------------------------------
Kinetic decay data

acid_soap...raman_peak_areas_ozone.txt - column 1 = time; column 2 = normalised C=C/C-H peak area ratio
oleic_acid_raman_peak_areas_ozone.txt - analogous to above

----------------------------------------------------------------------
IR spectra

...IR_spectrum.txt - column 1 = wavenumber (cm-1); column 2 = transmittance

----------------------------------------------------------------------
Raman spectra

...raman_spectrum.txt - column 1 = Raman shift (cm-1); column 2 = intensity

----------------------------------------------------------------------
Water uptake/loss experiment and model outputs

water...experiment_norm.txt - normallised experimental water content values for vertical scans across a levitated acid-soap particle; 
			      rows = vertical position number; columns = scan number (time)
water...modelfit.txt - normallised model water content values; 
                       note the greater time resolution, each time value is 323/1000 (number of model timepoints/number of experimental timepoints) of each experimental value;
		       rows and columns the same as above

----------------------------------------------------------------------
Hexagonal phase SAXS pattern

hexagonal_LLC_SAXS_pattern.txt - columns labelled with units
