Data provided by National Institute of Standards and Technology
Automated particle analysis (SEM/EDS) data from samples known to have been exposed to gunshot residue and from samples occasionally mistaken for gunshot residue - like brake dust and fireworks. The dataset consists of analyses of 30 discrete samples: 12 from sampling automobiles ("brake dust"), 10 from sampling fireworks ("sparklers" and "spinners" and "roman candles"), 8 from shooter's left or right hands. The analysis configuration meta-data for each analysis are contained in the "configuration.txt" and "script.py" files. The raw data from each analysis is in the file pair "data.pxz" and "data.hdz". The HDZ-file details the contents of the PXZ-file. In addition, the "mag0" directory contains TIFF images with embedded X-ray spectra for each particle in the dataset. Additional HDZ/PXZ files contain the results of reprocessing the "data.hdz/.pxz" in light of the "mag0" spectra and the standard spectra in "25 keV.zip" The samples came from Amy Reynolds ([email protected]) at the Boston Police Department. The "Shooter" samples were taken from a volunteer who fired a gun at a local firing range and was then sampled immediately after. They are part of a time series that was used to study GSR retention. The TIFF Image/Spectrum files can be read using NIST DTSA-II (https://www.nist.gov/services-resources/software/nist-dtsa-ii) or NeXLSpectrum.jl (https://doi.org/10.18434/M32286). The HDZ/PXZ files can be read using NIST Graf (available on request) or NeXLParticle.jl (https://github.com/usnistgov/NeXLParticle.jl).
