Flux variations (B vs. V) of HE 1136-2304 based on the SALT spectra. The blue dashed line is the best linear fit to the B vs. V fluxes. The black solid lines cover the upper and lower standard deviations of the interpolated AGN slope. The red dashed lines give the range of host slopes as determined by Sakata et al. (2010). The gray lines indicate the central B and V values of the host galaxy. Listed are the B and V flux values (in units of mJy and 10⁻¹⁵ erg s⁻¹ cm⁻² Å⁻¹) for the combined mean host galaxy+AGN flux, for the host galaxy flux, and for the mean AGN flux.
