Secondary Ion Mass Spectrometry data for regions of matrix in UOCs

Secondary Ion Mass Spectrometry (SIMS) data for regions of matrix in unequilibrated ordinary chondrites (UOCs). Included in this folder is:

• 20221010-raw-HDCSi.xls - data file containing all individual SIMS data points, including discarded. Each measurement is comprised of ~ 30 cycles, where individual cycle data can be found in the respective page with the same measurement number.
• 20221010-HDCSi-process.xls - data file containing calibration calculations, as determined by standards.
• Standards (.ods and .xlsx) - data file containing information on standards used, including sources, mean measurements, and known measurements.
• SIMS-Data-Processed.xlsx - data file containing processed SIMS data of only valid measurements, including calibrated δD, C (wt%), H₂O (wt%), and calculated D/H_H2O
• Raw Data - folder containing ascii files of the raw measurement data for each data point.
• Positions - folder containing visible light images of the position for each data measurement, where the dark square at the centre of the image is the position of the measurement.
• Plots - Folder containing (where available) interactive plots.
