RADIO/OPTICAL IDENTIFICATION of point sources
(Stewart, Muñoz-Darias & Fender in prep.)

Diagrams using Optical/IR/Radio fluxes and colours
o
The simpler the better
o
Quick identification of the nature of the transients:

" (simultaneous) Radio (few GHz), Optical (V/R bands):
★ Supernovae, Gamma Ray Burst
★ X-ray binaries, CVs, different flavours of pulsars
★ Active stars ( many thanks to Manuel Güdel)
