Visibility based angular power spectrum estimation in low frequency radio interferometric observations
Samir Choudhuri, Somnath Bharadwaj, Abhik Ghosh +1
We present two estimators to quantify the angular power spectrum of the sky signal directly from the visibilities measured in radio interferometric observations. This is relevant f…
