Notes. In Col. 1 are the source names in J2000 coordinates; Cols. 2–4 are core flux densities measured directly from images at 1400, 3000 and 6000 MHz, respectively; Cols. 5–7 are the spectral indices of the core emission calculated between 1400 MHz and 3000 MHz, 3000 and 6000 MHz and 1400 and 6000 MHz, respectively. Mark ‘–’ indicates unreliable measurements..
