Extended Data Fig. 1: Sample of observations in the four filters.
From: Evidence of haze control of Pluto’s atmospheric heat balance from JWST/MIRI thermal light curves
(observation 03, Oct 05, 2022). Top: pixel values in a 10”x10” RA,DEC field centered on Pluto’s expected position (MT_RA, MT_DEC). Background emission is evident. Bottom: background-corrected images. The value of the constant subtracted background and of the resulting maximum signal (MJy/sr) due to Pluto-Charon are indicated. Charon (to the north-east of Pluto) is much fainter than Pluto in F1500W, but brighter in F1800W, F2100W and F2550W because of its higher surface temperature.
