How do I find MWA data? How can I search for observations and figure out what they contain?

You can find the observation database at:
https://mwa-metadata01.pawsey.org.au
(email archive@mwa128t.org for username/password). Instructions for finding data are at:
http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/MetaDataWeb.
You can also execute those same commands from the command line using MWA_Tools/find_observations.pyThe best way to find MWA data and examine the contents is via the MWA All-Sky Virtual Observatory (ASVO) portal: https://asvo.mwatelescope.org 
Useful information on how to find MWA data is available on the Data Access wiki page.


How can I download files?

Use the MWA All Sky Virtual Observatory (ASVO) portal (https://asvo.mwatelescope.org). Once you register, you will be able find, convert and download MWA visibility data either through the web front end or via the command-line client. Please see https://asvo.mwatelescope.org/support to get started. By default, all users get access to publicly available data only, however, if you are the P.I. of a project, you can email asvo_support@mwatelescope.org and we'll enable you and your team to access to your project's proprietary data.


How do I reduce data?

http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/MWADRWorkshopA number of resources for the processing of Phase I MWA data are available on the Data Reduction wiki page. 


How do I find out what projects are ongoing? How do I join these projects?

...

The best way is to join the regular telecons done by the different groups. These are usually announced on the mailing lists for each group, but you can find a list of times at:
http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/TeleconTimes.To find out more, please refer to the appropriate team on the Science Information wiki page.

What is a Student Project? How do I make a Student Project?

The Student policy is described at: http://mwatelescope.org/teamavailable on the MWA Policies Page. A Student Project is “a well-defined research project that depends on MWA data, hardware, and/or software, and that will be conducted primarily by an undergraduate or postgraduate student in pursuit of his/her degree”. I.e., this is a way to protect a science area for students (PhD or other). You can find a list of MWA Student Projects at http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/StudentProjectson the Student Projects wiki page.

To make a new Student Project:

  1. Create a Student Project proposal (see examples) that clearly delineates the science goals and data sources.
  2. Check that this does not conflict with other Student Projects or  or other MWA Papers (http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/CollaborationPapers) Collaboration Papers.
  3. Send the proposal around to members@mwa-lfdmembers@lists.haystack.mit.edu for mwatelescope.org for feedback. If that is accepted, your Student Project will become active. Contact the Project Scientist with questions.

...

The MWA Publication policy is given at: http://mwatelescope.org/teamavailable on the MWA Policies page.
An MWA Publication is any journal/proceedings paper, popular article, or other publicly available document that has been derived from proprietary data, algorithms, software or hardware associated with the MWA, and in cases where these results have not been previously published elsewhere. So note that this includes proprietary data that has not yet been published.

The purpose of an MWA Publication is to delineate an area of science that will be published. The material contained in an approved MWA Publication cannot be published by other MWA Members. If you want to write a paper with proprietary data, you need to do it as a MWA Publication. You can find info about the required author list at: http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/CollaborationPaperson the Collaboration Papers wiki page. Note that this differs based on the original project and the science area.To create a MWA Publication

Please refer to the MWA Publication policy for full details, but in brief, the stages are the following:

  1. Create a an MWA Publication Proposal (see template and guidelines at the link above). This should be done before the paper is written. The Proposal contains the author list, the intended data source, the science/analysis goals, and the intended publication venue.
  2. Email the proposal around to: members@mwa-lfdmembers@lists.haystackmwatelescope.mitorg.edu In the case of problems, the situation will be moderated by the Project Scientist.
  3. Once the paper is ready, send around a draft to: members@mwa-lfdmembers@lists.haystack.mit.edu stating mwatelescope.org stating that the paper is ready for “Collaboration Review.” This requires a minimum of 2 weeks. Any issues should be discussed with the Principal Contact (i.e., you) and the Project Scientist.
  4. After all issues during the Collaboration Review have been resolved (and 2 weeks have passed), send around the latest version to the same email list stating that the paper is ready for “Final Review.” The Final Review also requires 2 weeks for Members to raise any issues, but only clear errors should be identified during this period.
  5. Submit the paper! And send the submitted version around to the same email address.

During refereeing, if the changes are minor you can deal entirely with the journal editor/referee. Then you only need to notify the Collaboration when your paper is accepted. If there are substantial changes then you can go back to Step 4 (Collaboration Review). Further questions or issues? Contact the Principal Scientist (scientist@mwatelescope.org).


I want to start a new project - who do I need to tell?

In general, nobody (but see below). But if you want to make sure that others are not going to do the same thing, create a Student Project (if a student is involved) or write a an MWA Publication.


Are there any additional steps needed for specific Science Collaborations?

  • Epoch of Reionisation (EoR): Please read the main EoR

...

  • page for details. Members of the EoR collaboration are expected to commit resources to the development of common analysis software and processing. Details are provided in the wiki, but potential new members are encouraged to contact Cath Trott (eor_lead@mwatelescope.org).
  • Galactic and Extragalactic (GEG)Please read main GEG page

...

  •  for details on current projects, to propose a new project, and to examine the GLEAM data.
  • Transients:

...

  •  No specific steps are needed for the Transients collaboration. Any MWA member can be a member of the Transients collaboration, and there are no special requirements for projects or papers. Contact
