Combining C-BASS maps with ancillary data to make temperature-temperature plots we find synchrotron spectral indices of $\\beta = -2.65 \\pm 0.05$ between 0.408 GHz and 5 GHz and $ \\beta = -2.72 \\pm 0.09$ between 1.420 GHz and 5 GHz for $-10^{\\circ} < |b| < -4^{\\circ}$, $20^{\\circ} < l < 40^{\\circ}$.
