  3. How do I get on MWA email lists? What lists exist?
    Email the Project Scientist. The available lists are given at:
    http://mwa-lfd.haystack.mit.edu/mailman/listinfo.
    There is a list for each main science area, as well as some technical lists and others dedicated to more specific topics.
  4. How do I get access to the MWA git repository?
    Email This email address is being protected from spambots. You need JavaScript enabled to view it. with a ssh public key attached as a separate file (not in-line). They will enable access to the MWA git repository. See
    http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/GitVersionControlIntro
    for usage.
  5. What is MWA_Tools, and how do I get MWA_Tools installed?
    MWA_Tools is the main set of user-contributed and user-supported tools to allow integration with the MWA observation and metadata databases.
    To get access to MWA_Tools, you need access to the git repository (see above). Then run:
    
    git clone This email address is being protected from spambots. You need JavaScript enabled to view it.:/MWA_Tools
    

    Email David Kaplan, Andrew Williams, Natasha Hurley-Walker, or Danny Jacobs for specific questions. This is also best discussed over the data analysis mailing list This email address is being protected from spambots. You need JavaScript enabled to view it..
    For installation instructions, see
    http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/MWA_Tools.

  6. What other software might I need?
    • NRAO’s CASA is useful for many things. See https://casa.nrao.edu.
    • Andre Offringa’s tools are also very useful. In particular, wsclean for imaging (https://sourceforge.net/projects/wsclean/) and the anoko/mwa-reduce tools (via This email address is being protected from spambots. You need JavaScript enabled to view it.:/anoko). RFI flagging is extensively tested with Andre’s AOFlagger (https://sourceforge.net/p/aoflagger/wiki/).
  7. 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 This email address is being protected from spambots. You need JavaScript enabled to view it. 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.py Run
     
    find_observations.py --help

    for usage.
    To find out the basic contents of an observation, run

    
    get_observation_info.py <obsid>

  8. How can I download files?
    Use the MWA_Tools/obsdownload.py script.
  9. How do I reduce data?
    http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/MWADRWorkshop
  10. How do I find out what projects are ongoing? How do I join these projects?
    First, check the MWA Student Projects and MWA Publication Proposals (see below). These contain specific projects submitted to the whole collaboration. If you wish to plan projects of your own, please make sure you plan accordingly. If you wish to join a project you can email the relevant Principle Contact, although note that there is no obligation to collaborate. Also note that some Science Collaborations may have specific lists or policies of their own (see below).
  11. How else do I find out what is going on?
    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.
  12. What is a Student Project? How do I make a Student Project?
    The Student policy is described at:
    http://mwatelescope.org/team.

    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/StudentProjects

    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 other MWA Papers (http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/CollaborationPapers).
    3. Send the proposal around to This email address is being protected from spambots. You need JavaScript enabled to view it. for feedback.
    4. If that is accepted, your Student Project will become active.
    5. Contact the Project Scientist with questions.
  13. What is a MWA Publication? How do I write a MWA Publication?
    The MWA Publication policy is given at:
    http://mwatelescope.org/team
    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/CollaborationPapers
    Note that this differs based on the original project and the science area.

    To create a MWA Publication:

    1. Create a 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: This email address is being protected from spambots. You need JavaScript enabled to view it.
    3. In the case of problems, the situation will be moderated by the Project Scientist.
    4. Once the paper is ready, send around a draft to: This email address is being protected from spambots. You need JavaScript enabled to view it. stating that the paper is ready for “Collaboration Review.” This requires a minimum of 2 weeks.
    5. Any issues should be discussed with the Principal Contact (i.e., you) and the Project Scientist.
    6. 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.
    7. Submit the paper! And send the submitted version around to the same email address.
    8. 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.
    9. If there are substantial changes then you can go back to Step 4 (Collaboration Review).
    10. Further questions or issues? Contact the Project Scientist (This email address is being protected from spambots. You need JavaScript enabled to view it.)
  14. 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 MWA Publication.
  15. Are there any additional steps needed for specific Science Collaborations?
    • EoR
      Please read the main EoR wiki page:
      http://mwa-lfd.haystack.mit.edu/twiki/bin/view/Main/EoR.
