• Call: import fullseye as fs; fs.ledger.phase_dictionary(phases, two_theta, wavelength, size=inf, K=0.9, instrumental_fwhm=0.02, lorentz='powder', eta=0.0) (to call the implementation directly, import pxrd; pxrd.phase_dictionary(phases, two_theta, wavelength, size=inf, K=0.9, instrumental_fwhm=0.02, lorentz='powder', eta=0.0); from the registry, opsdrive.get("phase_dictionary"))
Dictionary of phase reference patterns: on a 2θ grid, the 1-D intensity per volume fraction of 1 is arranged for each phase.

1 行 = (1/V²) Σ m|F|² L(2θ) × 形(形は Scherrer の size [Å] と装置の FWHM をガウスで足した幅の pseudo-Voigt、eta は Lorentz の割合)。instrumental_fwhm は数 [deg] か (2θ の列, FWHM の列) の表 —— 平らな検出器では画素の張る角が cos² 2θ で縮むので装置の幅は 2θ で変わる。広がりの無い標準(Si)の像を同じ幾何で積分し、diffraction_peaks の FWHM を表にして渡すのが筋(PoC の手順)。azimuthal_integrate を偏光・立体角の補正つきで回したプロファイルと同じ量に揃う。幅が合っていないと NNLS の倍率が偏る —— diffraction_peaks の FWHM と scherrer_size で size を先に見積もるのが筋。
返り値(dict): names・two_theta・matrix((P, n))・density [g/cm³]・phases(元の相、格子の追い込みで描き直すため)・params(波長・幅・Lorentz)。
Raises ValueError: 相が空・相の形でない、名前の重複、格子が増えない、幅の値が不正。
