Notes. Flux densities obtained from the VizieR database (Ochsenbein et al. 2000) via http://vizier.cds.unistra.fr/vizier/sed/. The unblurred, coadds of the Wide-field Infrared Survey Explorer (WISE) imaging (unWISE; Lang 2014); Diffuse Infrared Background Experiment (DIRBE; Smith et al. 2004; Price et al. 2010).(*) The 891 GHz HCN laser data observed in 2010 May 13 were used here.
