Extended Data Table 2 Recovered 21-cm profile amplitudes for various GHAs

From: An absorption profile centred at 78 megahertz in the sky-averaged spectrum

  1. Each block is centred on the GHA listed. The 6-h bins used the five-term physical foreground model (equation (1)) fitted simultaneously with the 21-cm profile amplitude between 64 MHz and 94 MHz. The 4-h bins used a six-term polynomial foreground model (equation (2)) fitted between 65 MHz and 95 MHz. All data are from hardware configuration H2. Sky temperatures are reported at 78 MHz.
