species.data.model_data.custom_model module#

Module for adding a custom grid of model spectra to the database.

species.data.model_data.custom_model.add_custom_model_grid(model_name: str, data_path: str, parameters: List[str], database: File, wavel_range: Tuple[float, float] | None, teff_range: Tuple[float, float] | None, wavel_sampling: float | None) → None[source]#

Function for adding a custom grid of model spectra to the database. The spectra are read from the data_path and should contain the model_name and parameters in the filenames in the following format example: model-name_teff_1000_logg_4.0_feh_0.0_spec.dat. The list with parameters should contain the same parameters as are included in the filename. Each datafile should contain two columns with the wavelengths in \(\mu\text{m}\) and the fluxes in \(\text{W} \text{m}^{-2} \mu\text{m}^{-1}\). Each file should contain the same number and values of wavelengths. The wavelengths should be logarithmically sampled, so with a constant \(\lambda/\Delta\lambda\). If not, then the wavel_range and wavel_sampling parameters should be used such that the wavelengths are resampled when reading the data into the species database.

Parameters:

model_name (str) – Name of the model grid. Should be identical to the model name that is included in the filenames.
data_path (str) – Path where the files with the model spectra are located.
parameters (list(str)) – List with the model parameters. The following parameters are supported: teff (for \(T_\mathrm{eff}\)), logg (for \(\log\,g\)), feh (for [Fe/H]), c_o_ratio (for C/O), fsed (for \(f_\mathrm{sed}\)), log_kzz (for \(\log\,K_\mathrm{zz}\)), and ad_index (for \(\gamma_\mathrm{ad}\)). Please contact the code maintainer if support for other parameters should be added.
database (h5py._hl.files.File) – Database.
wavel_range (tuple(float, float), None) – Wavelength range (\(\mu\text{m}\)). The original wavelength points are used if the argument is set to None.
teff_range (tuple(float, float), None) – Effective temperature range (K) for adding a subset of the model grid. The full parameter grid will be added if the argument is set to None.
wavel_sampling (float, None) – Wavelength spacing \(\lambda/\Delta\lambda\) to which the spectra will be resampled. Typically this parameter is not needed so the argument can be set to None. The only benefit of using this parameter is limiting the storage in the HDF5 database. The parameter should be used in combination with setting the wavel_range.

Returns:

None

Return type:

NoneType

species.data.model_data.model_spectra module#

Module for adding a grid of model spectra to the database.

species.data.model_data.model_spectra.add_model_grid(model_tag: str, input_path: str, database: File, wavel_range: Tuple[float, float] | None = None, teff_range: Tuple[float, float] | None = None, wavel_sampling: float | None = None, unpack_tar: bool = True) → None[source]#

Function for adding a grid of model spectra to the database. The original spectra had been resampled to logarithmically- spaced wavelengths, so with at a constant \(\lambda/\Delta\lambda\). This function downloads the model grid, unpacks the tar file, and adds the spectra and parameters to the database.
