Reconstruction error η of the 21 cm signal power spectrum calculated as an average over a multipole range, defined here as 30 ≤  ≤ 270, on each frequency channel of a dataset with MD80, considering two different numbers of realizations (Nrealis = 10 and Nrealis = 50). The value in parentheses is the average error over all channels in each dataset. The mean error for the Nrealis = 10 case is and for the Nrealis = 50 case is .
