  The hot Jupiter WASP-12b is one of the largest, hottest, and best-studied
extrasolar planets. We revisit our recent analysis of WASP-12b's emission
spectrum in light of near-infrared spectroscopic measurements which have been
claimed to support either a hydride-dominated or carbon-rich atmospheric
composition. We show that this new spectrum is still consistent with a
featureless blackbody, indicating a nearly isothermal photosphere on the
planet's day side. Thus the ensemble of occultation measurements for WASP-12b
is still insufficient to constrain the planet's atmospheric composition.
