Description

There are very few instruments with the capabilities that MWA provides. However, unlocking the full potential of the MWA archive requires bespoke software to deal with some of its idiosyncrasies. In this workshop, participants will be given the tools to download, preprocess, calibrate and image almost any correlated MWA observation.

Starting with a representative sample of raw MWA visibility files (Phase I & II, Legacy correlator & MWAX), we will preprocess those raw files with Birli, demonstrate how to perform quality analysis and flagging, calibrate with hyperdrive, and image with wsclean.

The software for this workshop has been fully containerized, and can run offline on any machine capable of emulating linux-x86 (this includes arm64-based macs running the latest Docker). The demo website will be updated with more details closer to the event about what you need to download in order to prepare your machine for the demo.

Dev Null [they/them] is a contributor to many MWA software projects, including the Birli preprocessor, and hyperdrive calibration suite. Dev is currently working with the Epoch of Reionozation team on a data quality analysis pipeline which has processed ~600 hours of MWA EoR observations from 2013 to present. This work is part of the Australian SKA Regional Centre's efforts to support precursor instruments.

Timeslot preferences This is an hour long workshop, but happy to cut it down to a 30 minute talk
