GridKit File Format

All StarKit input grids are stored in an HDF5 file. It consists of three parts:

  1. The index is stored as a pandas DataFrame (through HDFStore) on the key ‘index’.
  2. The flux array is stored as a 2D array using h5py under the key ‘fluxes’

The metadata is stored as a pandas Series (through HDFStore) on the key ‘meta’

The current version of StarKit requires the following metadata:

flux_unit astropy compliant unit
grid_bibtex bibtex for stellar grid
grid_name Grid Name
resolution_profile only ‘gaussian’ supported at this time
resolution_sampling how many pixels per resolution element
resolution_type r_const or delta_lambda_const
uuid UUID4
wavelength_unit astropy compliant unit
