KN Sim Parser
This is a simple Rust utilty that parses the .dat spectrum files from Wollaeger et al 2021 into individual HDF5 files.
The data files are obtained from https://zenodo.org/record/7335961.
The parser does no transformations or unit conversions on the file data. It only parses the UTF-encoded numerical data in the input files into single precision floating point (f32) values, and dumps these into multidimensional arrays in the HDF5 files.
Build
Build the project with cargo as normal for Rust packages.
This package requires a local installation of an HDF5 library for the Rust hdf5 crate to compile against. If the automatic build process cannot locate the library, it can be directed by setting the HDF5_DIR environment variable. See the hdf5 Rust crate documenation for more details https://docs.rs/hdf5/latest/hdf5/.
Output Data Layout
The output HDF5 file has 10 fields, all Datasets:
topo: Integer, i32, 0 ("S") or 1 ("P"), denoting the topology of the simulation.wind: Integer, i32, 1 or 2, denoting the type of lanthanide wind.md_Msolar: float, f64, mass of dynamic ejecta in Solar Masses.vd_c: float, f64, speed of dynamic ejecta in c.mw_Msolar: float, f64, mass of wind ejecta in Solar Masses.vw_c: float, f64, speed of wind ejecta in c.t_days: array, size[Nt], f32. Time of fluxes in days.lambda_cm: array, size[Nl, 2], f32. Wavelength bins (lower then upper) in cm.theta_rad: array, size[Nv, 2], f32. Viewing angle bins (lower then upper) in rad.fla_cgs_per_angstrom: array, size[Nt, Nl, Nv], spectral flux density f_lambda in (erg / (s cm^2 A))
