Cold Ion Measurements Enabled by Electrostatic Instrument Biasing: Implementation and Modeling Results This archive contains the data file for the five CPIC simulations run for paper Larsen et al 2019. [1, 2]. The data files contents and format are described. Each data file is stored in HDF5 format written with h5py [3, 4]. The files named field_potential_bias_XX_data.h5 contain the electric field components and electric potential with the following structure: + :|____Author (str [50]) :|____Bias (str [3]) :|____DOI (str [22]) :|____Date (str [14]) :|____Description (str [81]) :|____File_Creator (str [44]) :|____License (str [2140]) |____E (h5py._hl.dataset.Dataset (3, 101, 101, 101)) :|____Description (str [41]) :|____Format (str [94]) :|____Units (str [3]) |____XYZ (h5py._hl.dataset.Dataset (3, 101)) |____phi (h5py._hl.dataset.Dataset (101, 101, 101)) See the metadata within the file for units of each variable. The files named detector_bias_XX_data.h5 contain the particles collected at the simulated detector in a mix of physical and CPIC units with the following structure: + :|____Author (str [50]) :|____Bias (str [4]) :|____DIO (str [22]) :|____Date (str [14]) :|____Description (str [81]) :|____Detector_area (str [11]) :|____File_Creator (str [44]) :|____License (str [2140]) :|____Timestep (str [12]) :|____Timestep_description (str [114]) :|____electron_temperature (str [6]) :|____photoemission_electron_energy (str [4]) :|____potential_at_boundary (str [3]) :|____proton_electron_mass_ratio (str [4]) :|____proton_temperature (str [7]) :|____reference_density (str [9]) |____Energy (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [32]) :|____Units (str [2]) |____Velocity (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [59]) :|____Units (str [3]) |____Velocity_CPIC (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [59]) :|____Units (str [4]) |____Vx (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [44]) :|____Units (str [3]) |____Vx_CPIC (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [44]) :|____Units (str [4]) |____Vy (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [44]) :|____Units (str [3]) |____Vy_CPIC (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [44]) :|____Units (str [4]) |____Vz (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [44]) :|____Units (str [3]) |____Vz_CPIC (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [44]) :|____Units (str [4]) |____phi (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [41]) :|____Units (str [3]) |____q (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [47]) :|____Units (str [4]) |____species (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [26]) |____theta (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [37]) :|____Units (str [3]) |____timestep (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [41]) |____weight (h5py._hl.dataset.Dataset (2296,)) :|____Description (str [38]) :|____Units (str [4]) The information in parentheses are the datatype and size, square brackets, [], denote a single element of that many characters and parentheses, (), denote the stored array size.
