MWA EoR Raw Data All Bands 2014-2015

The Epoch of Reionisation project with the Murchison Widefield Array (MWA) observes three fields in the cold sky to detect neutral hydrogen from the first billion years of the Universe. Observations span August-February when the Galactic Plane is below the horizon, with data obtained from every observing season since 2013. Multiple studies by the international MWA EoR Collaboration and our data quality metric show that the 2014 and 2015 seasons (August 2014 - March 2015 inclusive) contain the least contaminated data, and these sets have been used for scientific analysis. This allocation preserves the raw telescope data across the full suite of EoR observations (ultralow, low, and high-bands). The dataset has also been used for a lot of ancillary science, including providing a high-cadence 18-month observation of the same fields for transient and variable astrophysical sources. Details of the EoR observing fields and processing are presented in D. Jacobs et al (2016), and a full census of our data from 2013-2017 was presented in C. Trott et al (2020).
