All-sky galactic radiation at 45 MHz and spectral index between 45 and 408 MHz.

Abstract (from CDS):

We study the Galactic large-scale synchrotron emission by generating a reliable all-sky spectral index map and temperature map at 45MHz. We use our observations, the published all-sky map at 408MHz, and a bibliographical compilation to produce a map corrected for zero-level offset and extragalactic contribution.We present full sky maps of the Galactic emission at 45MHz and the Galactic spectral index between 45 and 408MHz with an angular resolution of 5°. The spectral index varies between 2.1 and 2.7, reaching values below 2.5 at low latitude because of thermal free-free absorption and its maximum in the zone next to the Northern Spur.
