Example of the bowtie analysis for a single main rate channel ($E_0\approx 80\text{keV}$) from LOW-A (LUT 16386). The green curve is the simulated isotropic pixel response and the black and grey curves are the candidate exponential and power law bowtie spectra ($=y_i/j_i(E_0)$), respectively. The red line marks the energy channel width and the red dot marks the energy channel centroid, $E_0$. Note that the labels on the horizontal and vertical scales are different for the isotropic response and the candidate spectra. The response curve is the simulated isotropic response ($\overline{R}$) plotted against incident electron energy ($E_{\mathrm{inc}}$), while the candidate spectra are bowtie response parameter ($G_0\mathrm{\Delta }E$) vs. bowtie energy centroid ($E_0$)
