Emission in pixel A. Upper left: image of the scaled intensity I_λ(x, y, t)/I_cont(x, y, t) in He I 1083 nm. Upper-middle: λt-slice of the scaled intensity at the location of the red square in the image. The red tick marks indicate the wavelength and time of the image. Upper right: light curve at the spatial location indicated by the square and the wavelength indicated by the tick marks. The bottom row shows the same for Ca II K, except that the image in the lower-left panel shows I_λ, i.e., it is not scaled to the local continuum intensity.
