This data set consists of both measured and simulated optical intensities scattered off periodic line arrays, with simulations based upon an average geometric model for these lines. These data were generated in order to determine the average feature sizes based on optical scattering, which is an inverse problem for which solutions to the forward problem are calculated using electromagnetic simulations after a parameterization of the feature geometry.

Viscosity data for normal alkanes (methane, ethane, etc.) taken from the literature to accompany the paper "Entropy Scaling of Viscosity -- II: Predictive Scheme for Normal Alkanes". The data were obtained from an internal version of the NIST ThermoDataEngine database version 10.4.2. File contents include

This dataset includes files generated from post-build X-ray computed tomography (XCT) measurements of the four parts built as part of the "Overhang Part X4" in-situ process monitoring dataset (available at https://doi.org/10.18434/M32233). The "Overhang Part X4" dataset was a three-dimensional (3D) additive manufacturing (AM) build performed on the Additive Manufacturing Metrology Testbed (AMMT) by Ho Yeung and Brandon Lane on June 28, 2019.

Supplemental data for "Comparison of measured and simulated spin-wave mode spectra of magnetic nanostructures" by H. T. Nembach, R.D. McMichael, M.L. Schneider, J.M. Shaw, T.J. Silva.

NeXLSpectrum is a collection of tools for reading, writing and processing X-ray spectra. It includes methods to read common spectrum and hyperspectrum formats, extract spectral data, plot the spectra with common spectrum markers, and perform filter-fitting. The fitting algorithm has been optimized for both speed and low memory usage (<1 ms and 160 kB per spectrum for 6 elements on a single thread).

In-situ Raman spectroscopic measurements were conducted during indentation of fused silica (FS) samples. The experiments were conducted using Raman spectroscopy-enhanced instrumented indentation testing (RS-IT). RS-IT was developed at the National Institute of Standards and Technology (NIST) and employs an in-house built instrumented indentation testing device that is coupled to a custom Raman microscope.[Rev. Sci. Instrum. 83 125106 (2012)]
