a Example image of “2 h-averaged count,” \(\overline{{\varvec{I}} }\). Equivalent counts in each pixel are plotted in b as a function of the elevation angle with black symbols. The red line shown in b is the “elevation angle averaged count,” \(\overline{{\varvec{I}} }\left(\mathbf{\Phi }\right)\). c Amplitude of the residual components (\(\overline{{\varvec{I}} }-\overline{{\varvec{I}} }\left(\mathbf{\Phi }\right)\)) to the \(\overline{{\varvec{I}} }\left(\mathbf{\Phi }\right)\)
