tardis.io.model.readers.generic_readers module¶
- tardis.io.model.readers.generic_readers.read_csv_composition(fname, delimiter='\\s+')[source]¶
Read composition from a simple CSV file
The CSV file can contain specific isotopes or elemental abundances in the different columns. The first row must contain the header in which the contents of each column is specified by the elemental symbol (for elemental abundances) or by the symbol plus mass number (for isotopic abundances).
Example: C O Fe Ni56 Co
The i-th row specifies the composition in the i-th shell
- fnamestr
filename of the csv file
- tardis.io.model.readers.generic_readers.read_simple_ascii_abundances(fname)[source]¶
Reading an abundance file of the following structure (example; lines starting with hash will be ignored): The first line of abundances describe the abundances in the center of the model and are not used. #index element1, element2, …, element30 0 0.4 0.3, .. 0.2
- Parameters:
- fnamestr
filename or path with filename
- Returns:
- indexnp.ndarray
containing the indices
- abundancespandas.DataFrame
data frame containing index, element1 - element30 and columns according to the shells
- tardis.io.model.readers.generic_readers.read_simple_ascii_density(fname: Any) Tuple[Quantity, Quantity, Quantity][source]¶
Reading a density file of the following structure (example; lines starting with a hash will be ignored): The first density describes the mean density in the center of the model and is not used. 5 s #index velocity [km/s] density [g/cm^3] 0 1.1e4 1.6e8 1 1.2e4 1.7e8
- Parameters:
- fnamestr
filename or path with filename
- Returns:
- time_of_modelastropy.units.Quantity
time at which the model is valid
- velocityu.Quantity
velocity
- mean_density: u.Quantity
mean density
