SED for COCONUTS-2 b. We show in orange the Gemini/FLAMINGOS-2 spectrum (Z. Zhang et al. 2025), in blue the G395H NIRSpec JWST spectrum, and in brown points the MIRI photometry. We also included photometry from the literature. MKO label (green, in increasing wavelength): Gemini/FLAMINGOS-2 Y, J_MKO (NSFCam J), H_MKO (NSFCam H), and K_MKO (NSFCam K); WISE label (red): W1 (WISE W1), W2 (WISE W2), and W3 (WISE W3); Spitzer label (purple): [3.6] (IRAC I1) and [4.5] (IRAC I2); and MIRI label (brown): MIRI F1000W, MIRI F1280W, and MIRI F1800W. See Table 1 for the magnitude of each photometry point. The gray line represents the connecting lines, as well as the Wien and RJ approximations, extending beyond the existing data.
