The following table gives a description of the radio observations that served for the calculations of the radio flux density upper limits at 1.4 GHz listed in Table 1 of Pletsch, Guillemot, Allen et al., ApJ Lett. 779, 11 (2013). For details on the observation configurations, on telescope characteristics, and on the calculation of the flux density upper limits, refer to Pletsch et al., ApJ Lett. 779, 11 (2013) and Pletsch et al., ApJ 744, 105 (2012).
