(PFB) boards that convert the 1.28 MHz coarse frequency channels into channels with 10 kHz frequency resolution in preparation for cross-correlation. Correlator boards then cross-multiply signals from all tiles to form visibility data. A distributed clock signal drives the coherence of receivers in the field and maintains timing for the correlator. This system is only capable of ingesting the data from 128 tiles and thus while the array currently comprises 256 tiles, only half of the tiles are correlated at a time, giving rise to the two configurations discussed above. The MWA Collaboration plan to replace this correlator in the near future with a newer machine, capable of ingesting the data from all 256 tiles. The MWA is operated remotely through an interface to a Monitor and Control (M&C) software package resident on a dedicated computer located within the CSIRO Data Processing Facility at the MWA site. The M&C software maintains a state-based description of the hardware and an event-driven database describing the observation scheduling of the Instrument. M&C software commands several elements of the system including pointing and tracking of the beamformers, frequency selection of the receivers, correlation parameters for the correlator, and RTC/RTS functions, amongst others. The M&C system contributes to the MWA archive by storing instrument "metadata" into an external database. This includes both the instrument configurations for each observation and also housekeeping information collected from various hardware components. Data are transferred from the site to the MWA archive located at the end of a high-bandwidth network connection. The primary MWA data archive is located in Perth at the Pawsey Supercomputing Centre. As of December 2018 the resultant initially calibrated data are then provided to the international astronomical community via the MWA node of the Australian All-Sky Virtual Observatory (ASVO). Significant processed data products produced by the MWA Collaboration such as the initial release of the GLEAM survey are also available via various international scientific databases for subsequent analysis and interpretation. Project partners During Phase I, the MWA consortium initially comprised 110 individual researchers drawn from 12 institutions from Australia, NZ, the US, and India. New Zealand joined the consortium in late 2011 and an additional two institutions from the US were added in 2014 taking the total number of Phase I partner organisations to 14. By the end of Phase I there were 160 individual research scientists involved in the MWA. Membership of the MWA consortium
