Histograms of variables from fitting individual I(q) profiles of N = 33 cells. The y-axes represent the number of counts. The heterochromatin and euchromatin distributions are shown in orange and blue, respectively. The cytoplasm distributions are gray. (a) The exponent α, equation (3), from fitting I(q) profiles in the [q0, qmin] range where α ≠ −4. (b) The Porod constant K, derived from fitting profiles in the [qmin, qmax] range where α = −4. (c) The projected mass density (black axis labels), projected electron density (red axis labels) and phase shift (green axis labels). The number of bins is calculated using Scott's rule (Scott, 1979). The median values of each distribution are listed in Table 1. |
