TL;DR: The Hydrogen Epoch of Reionization Array (HERA) is a staged experiment to measure 21 cm emission from the primordial intergalactic medium (IGM) throughout cosmic reionization as discussed by the authors.

TL;DR: Kohn et al. as discussed by the authors performed a simple image-based calibration based on the unpolarized diffuse emission of the Global Sky Model, and showed that it achieves qualitative redundancy between the nominally redundant baselines of the array and reasonable amplitude accuracy.

TL;DR: In this paper, the authors employ the closure phase spectra for redundant triads to estimate departures from redundancy for redundant baseline visibilities, and show that the median absolute deviation from redundancy in closure phase across the observed frequency range of about 4.5deg.
