Maps of the seven CLASH objects identified as possible neutrino sources. Black circles show nominal neutrino positions. Dashed lines show the 90% confidence error regions, and the solid lines show the elliptical approximation. The CLASH FSRQs are indicated by red crosses. Green squares show BZCat blazars, and purple ellipses the Fermi catalogue element 90% confidence error regions. The small blue crosses are the S11 quasar positions.
