The Landecker & Wielebinski 150 MHz all-sky map.

Patra et al. 2015, provided a recalibration of the 150 MHz map based on comparison with absolutely calibrated sky brightness measurements between 110 and 175 MHz made with the SARAS spectrometer, and Monsalve et al. 2021, provided a recalibration based on comparison with absolutely calibrated measurements from the EDGES. The correction factors that were obtained are SARAS: scale 1.048 +- 0.008, offset -22.4 +- 8.0 K EDGES: scale 1.112 +- 0.023, offset 0.7 +- 6.0 K Monsalve et al. note that the differences may be because EDGES is a southern hemisphere instrument, SARAS is a northern hemisphere instrument, and the all-sky 150 MHz map was constructed from separate southern, northern, and intermediate declination surveys
