Four montages of the first several terms in the generalized spherical harmonic expansion of the temperature map in the h_mℓ basis. Each montage corresponds to a different combination of α and ω_drag, labeled in the upper right of each quadrant. Each map shows the temperature perturbation (purple to yellow is cold to hot) as a function of latitude and longitude (shown in Moll weide projections such that the sub stellar longitude is in the center of the plot). The m = 0 terms are always zero. The even-ℓ terms are asymmetric about the equator and therefore do not represent typical GCM results in equilibrium, so we keep all even-ℓ power coefficients fixed to zero in the subsequent fits (this approach assumes edge-on orbits, for exceptions see Cowan et al. 2017). In the upper two quadrants, when ω_drag is set to a smaller value, the chevron shape becomes more pronounced. In the two quadrants on the right, when the α is set to a larger value, the concentration of heat near the equator is more pronounced.
