^a RA, Dec, and the positional errors (90% containment) were taken from GCN Reports (http://gcn.gsfc.nasa.gov/report_archive.html) for GRB 061110A - GRB 071003 and GCN Circulars otherwise. ^b Fluence and $T_{\rm 90}$ data for GRB 050726 - GRB 070612B were taken from Sakamoto et al. (2008) except that $T_{\rm 90}$ of GRB 060505 was taken from Palmer et al. (2006). Fluence and $T_{\rm 90}$ data of GRB 030329 and GRB 030821 were taken from Sakamoto et al. (2005), and those of GRB 041006 from Shirasaki et al. (2008). Other data were taken from GCN Circulars and HETE pages (http://space.mit.edu/HETE/Bursts). ^c X: X-ray, O: optical, R: radio; `` $\surd$ '' indicates the detection of a counterpart, `` $\times$ '' a null detection, and ``.'' that no measurement was reported in the corresponding energy range, from http://grad40.as.utexas.edu/grblog.php ^d The relative expected VHE flux for each GRB is ranked according to the empirical scheme described in Sect. 3.3. ^e Perley et al. (2008). ^f Cucchiara et al. (2007). ^g Malesani et al. (2007). ^h Redshift of a candidate host galaxy Berger & Fox (2007). ⁱ Fynbo et al. (2007). ^j Berger & Gladders (2006). ^k Ofek et al. (2006). ^l Redshift according to de Pasquale et al. (2007), based on afterglow modelling. ^m Although this burst was referred to as GRB 041211 in various GCN Circulars, the proper name GRB 041211B (e.g., in Pélangeon et al. 2006) should be used to distinguish it from another burst, GRB 041211A (=H3621) which occurred earlier on the same day (Pélangeon, A., private communication). ⁿ Soderberg et al. (2006). ^o The position error of this burst is large, see Fig. 3. ^p Stanek et al. (2003).
