Plot of a spherical, expanding-atmosphere CMFGEN model spectrum, appropriate for an O supergiant star (red), normalized to a reference plane-parallel ATLAS9 spectrum (black). Optical (Johnson UBV), near-IR (JHKs), and mid-IR (Spitzer/IRAC) photometric bands are overlaid. The CMFGEN spectrum shows elevated IR continuum emission and emission lines produced in the stellar wind that change the spectral shape in the mid-IR bands.
