Optimizing spectral stacking for 21-cm observations of galaxies: accuracy assessment and symmetrized stacking
We present an assessment of the accuracy of common operations performed in 21-cm spectral line stacking experiments. To this end, we generate mock interferometric data surveying the 21-cm emission at frequency 1310 < ν < 1420 MHz (0.005 < z < 0.084) and covering an area ~6 deg 2 of the sky, mimicking the observational characteristics of real
