Additional Information: Funding Information: We are grateful to T. Hung for sharing a Python implementation of the relativistic accretion disk model, and we thank T. Ricci, J. Schimoia, and G. Couto for providing spectra of NGC 4958, NGC 1097 and Arp102B. We also thank J. Krolik, T. Piran and T. Ryu for insightful comments, and the anonymous referee for comments and suggestions that improved the paper. This work is based on observations collected at the European Southern Observatory under ESO programmes 106.216C, 106.2169.001 and 106.2169.002 (PI: Inserra). The spectra will be made publicly available through WISErep. We thank the Swift team for scheduling the requested ToO observations. The Swift data are publicly available from the Swift science archive. This work is partly based on the NUTS2 programme carried out at the NOT. NUTS2 is funded in part by the Instrument Centre for Danish Astrophysics (IDA). Based on observations made with the Nordic Optical Telescope, owned in collaboration by the University of Turku and Aarhus University, and operated jointly by Aarhus University, the University of Turku and the University of Oslo, representing Denmark, Finland and Norway, the University of Iceland and Stockholm University at the Observatorio del Roque de los Muchachos, La Palma, Spain, of the Instituto de Astrofisica de Canarias. This work makes use of observations from the Las Cumbres Observatory global telescope network. Based on data products created from observations collected at the European Organisation for Astronomical Research in the Southern Hemisphere under ESO programme 179.A-2010 and made use of data from the VISTA Hemisphere survey (McMahon et al. 2013).
