Notes.
Spectral indices between the indicated frequencies (in MHz).
Average spectral index obtained using values at 402, 735, 887, 943, and 1425 MHz.
Spectral index obtained by fitting flux densities at 1425, 4860, and 8689 MHz.
When more than two data points are used for fitting, the error in α reflects the fitting error, while for cases with only two points, the analytical error in α is obtained using the uncertainties package in Python.
