filters_to_fft_table

synphot.filter_parameterization.filters_to_fft_table(filters_mapping, n_terms=10)

Run filter_to_fft() on a list of filters and store results in a table.

Parameters:

filters_mappingdict

Dictionary mapping human-readable filter name to its SpectralElement and wavelengths, if applicable. If the filter object has a valid waveset, just provide None for wavelengths; otherwise provide a Quantity array for sampling. For example:

{'JOHNSON/V': (<SpectralElement ...>, None),
 'Flat': (<SpectralElement ...>, <Quantity [1000., ..., 9999.] Angstrom>)}

n_termsint

Number of FFT parameters to keep.

Returns:

fft_tableTable

Table storing FFT parameterization for the given filters. Use its write method to save it to file.
