Brightness maps corresponding to the three full orbit phase curves of WASP-43b (Stevenson et al. 2014, 2017). Here, ϕ is the longitude from the substellar point, and the nightside of the planet is shown as the gray shaded area. All three phase curves require negative brightnesses at certain longitudes, which is unphysical. The red line shows where we doctor the maps by setting the brightness to zero.
