v0.4.4

  • add parseGasMixture helper to parse gas mixtures from runtime values
  • ignore some low hanging performance fruit by avoiding zip
  • add absorption for gases (1 - transmission)

v0.4.3

  • add support for transmission output in examples/calc_gas_mixtures for solids
    • improve output filenames a bit more
    • replace μ symbol in output file names by u for compatibility

v0.4.2

  • change examples/calc_gas_mixtures.nim to not use half width space in filenames, use dot instead

v0.4.1

  • add basic CI running test / playground
  • compile examples as static linux binary
  • extend gas fraction example to include calculation of transmission data

v0.4.0

  • add staticBuild option and default to runtime elements. -> Compile with -d:staticBuild to read all data files at compile time to have a binary that can be moved around without shipping the CSV data files.
  • add pairs iterator for GasMixture and export one for Compound
  • add helper pressure to compute pressure given temp and density
  • move getFluorescenceLines above the plotting helpers
  • deprecated molarWeight for compounds (-> molarMass), add for gases
  • do not default to 3 digits of precision for gas mixtures
  • minor fixes in compound macro for construction
  • add helper to parse a compound from a given string
  • give runtime elements their name as field

v0.3.1

  • fix project structure to follow annoying nimble rules
  • add missing dependencies

v0.3.0

  • add support for form factor files from NIST (useful for energies above 30 keV)
  • adds a tool to download all data from NIST (files are shipped with the libraries though)
  • do not return NaN below 30 eV (lower energies defined in Henke files)

v0.2.1

  • Elements now have a density field as well, which can be handed to the init call (in the future we might look them up as well).
  • Compounds can also be given a density in the compound macro by providing a ρ or density argument.
  • The DepthGradedMultilayer type takes care of constructing the correct refractive indices & layers for such a coating.
  • add depthGradedLayers helper to compute the layer thicknesses according to the equations for depth graded layers
  • export ρ field for compounds
  • add density for gas mixtures to get density of the mixture
  • add transmission to compute the transmission of gas mixtures

v0.2.0

  • add refractedAngle, refractedAngleSin to get refracted angle after an interface (and the sin(θ_j) in the latter case)
  • add energy to convert a wavelength back to an energy
  • add support for depth graded multilayer reflections, i.e. like the LLNL telescope (NuSTAR optic)
  • improve reflectivity implementation
  • allow calculation of refractive indices for compounds

v0.1.3

  • add transmission overload for convenience taking a compound, density, length and energy

v0.1.2

  • add FluroscenceLine type and CSV file: CSV file contains all known X-ray fluorescence lines and their intensities. Using getFluorescenceLines the user can get all lines, their names and their relative intensities (be careful to normalize!).
  • add GasMixture type and option to compute absorption length and attenuation coefficient for a gas mixture

v0.1.1

  • fix attenuation coefficient interpolation from NIST data
  • use NIST attenuation coefficients for > 30 keV for now instead of computing from f1, f2
  • allow more parameters in plotting of attenuation and transmission
  • change naming of some resource files

v0.1.0

  • initial release with basic features
