Notes.In the third column we show 5-σ upper limits on the radio flux or the detected flux and 1-σ uncertainty. Δt denotes the time of the radio observation with respect to the estimated time of disruption (tD). The radio observation of the first five candidates were published before mid-2012, the last six are taken from Bower et al. (2013). We note that most of the TDF candidates that were discovered in the nineties also have post disruption radio upper limits from large radio surveys (e.g., NVSS, Condon et al. 1998), these are listed in Komossa (2002).
