[docs]class MiriResolutionModel(ResolutionModel): """ A data model for MIRI Resolution reference files. Parameters __________ data : numpy table Resolving Power table A table containing resolving power of the MRS. THe table consist of 11 columns and 12 rows. Each row corresponds to a band. The columns give the name of band, central wavelength, and polynomial coefficeints (a,b,c) needed to obtain the limits and average value of the spectral resolution. psf_fwhm_alpha_table : table PSF FWHM Alpha A table with 5 columns. Column 1 gives the cutoff wavelength where the polynomials describing alpha FWHM change. Columns 2 and 3 give the polynomial cofficients (a,b) describing alpha FWHM for wavelengths shorter than cuttoff. Columns 4 and 5 give the polynomial coefficients (a,b) describing alpha FWHM for wavelengths longer than the cutoff. psf_fwhm_beta_table : table PSF FWHM Beta A table with 5 columns. Column 1 gives the cutoff wavelength where the polynomials describing alpha FWHM change. Columns 2 and 3 give the polynomial cofficients (a,b) describing beta FWHM for wavelengths shorter than cuttoff. Columns 4 and 5 give the polynomial coefficients (a,b) describing beta FWHM for wavelengths longer than the cutoff. """ schema_url = "http://stsci.edu/schemas/jwst_datamodel/miri_resolution.schema"
