tokens: Acknowledgements We acknowledge the help of Roberto Menezes, Rogério Riffel, and Rogemar Riffel in reducing a Gemini spectrum of NGC 3115, the continuum of which unfortunately was dominated by stellar emission and contained no information on the LLAGN. We acknowledge useful discussions with João Steiner, Alexander Tchekhovskoy, and Massimo Gaspari. This work was supported by FAPESP (Fundação de Amparo à Pesquisa do Estado de São Paulo) under grants 2015/26831-1 and 2016/24857-6.
