Speckle spectral field for HD 19467 B. a. The annular slice of the integral field unit used to extract the speckle model spectra was adopted from Ruffio et al. (2024). b. Spectra from individual pixels in the annular slice of the IFU (n = 120 pixels). c. PCA reconstruction of the speckle spectra with 30 components. From top to bottom, we show the components with the largest fitted amplitudes. d. Amplitude of the five speckle components with the largest amplitude from the joint atmospheric and speckle fit. e. Combined speckle model from the best-fit retrieval.
