Notes. We also provide the brightness temperature in total intensity at 408 MHz (Remazeilles et al. 2015)and 1.4 GHz (Reich & Steffen 1981; Reich & Reich 1986; Reich et al. 2001), the brightness temperature of the polarised intensity at 1.4 GHz (Wolleben et al. 2006), the brightness temperature of the total intensity scaled down from 408 to 130 MHz using the spectral index from Guzmán et al. (2011), and the calculated polarisation fractions at 130 MHz and 1.4 GHz.
