Notes. The spectral indices were calculated from flux density measurements in (1) the TGSS and the GMRT 610 MHz maps; (2) the GMRT 610 MHz and the FIRST 1.4 GHz maps; (3) the TGSS and the NVSS 1.4 GHz maps. The first line gives the systematic uncertainties on α for a 10% systematic uncertainty on each flux density measurement. The other uncertainties listed in the table are statistical. The meanings of the \ and ∪ symbols were given in the notes of Table 3.
