ASKAP Update for May
The ASKAP update for May reports on the resumption of survey operations, plans for a dedicated RFI environment survey, and the upcoming call for guest science proposals. The figure above is a summary plot of the data flagging statistics from roughly 1000 hours of various survey observations since 2019, with observing frequency on the y-axis and time of day on the x-axis. In the parts of the band used for surveys, roughly 3% of the recorded data is flagged. Note that the gap between about 1100 and 1300 MHz is badly impacted by global navigation system satellites and is discarded before processing, so it does not influence these statistics. For the remaining science bands, we lose a total of about 20 MHz to aeronautical radio navigation, and 10 MHz each to fixed mobile and mobile satellite services. (Image credit: Liroy Lourenco)
