Caption: Figure 3.
HEALPix maps of the dark ages 21 cm brightness-temperature fluctuations in mK, with the monopole removed. Each panel shows a Mollweide projection of the entire sky, all pixels having equal area. The panels show maps of the dark ages at z ∼ 100 to near its global brightness-temperature peak absorption at z ∼ 50.
