Information on how to become an External Collaborator, and a list of active External Collaborators with their projects, including start dates and status.

This page is the External Collaborators Wiki as referenced in the Apertif Participation and Data Usage Policy document. The External Collaborators Wiki is the system by which details pertaining to projects based on proprietary Apertif data with External Collaborators are tracked and shared with the Apertif science team.

External Collaborators are described in Section 2.2.3 of the Apertif Participation and Data Usage policy. They agree to abide by the Apertif Publication Policy, the Code of Conduct outlined in Section 8 of the Apertif Participation and Data Usage Policy, and the Netherlands Code of Conduct for Research Integrity.

Apertif Participants or Builders who wish to support the proposal for an External Collaborator(s) (EC) should first make the EC aware of the Apertif Participation and Data Usage Policy and the Apertif Publication Policy which may be found here. Using this wiki implies that the EC and their sponsoring Apertif member have read and will abide by these policies.

External collaborators are approved through a written proposal submission to the Apertif Survey Executive (ASE; chair Betsey Adams adams@astron.nl). Submissions should concisely describe the project that will be undertaken, why access to proprietary Apertif data is necessary, what Apertif data products will be used, and what contribution the EC brings to Apertif that is not already available within the Apertif team. There are no length requirements, but proposers are encouraged to keep proposals to less than a page if possible.

After approval by the ASE, the EC or their Apertif sponsor should add the details of the project in the table below. External collaborators may be granted access to this wiki by…

External Collaborations are listed in the table below. When adding an external collaboration please follow these instructions:

• Newly approved EC projects must be added to the top of the table (i.e., reverse chronological order).
• An existing row in the table may not be removed. All changes must be captured within the row. If a project has been scrapped, Strike-through Text must be used in the relevant row(s).
• The following list provides instructions and/or notes for each of the columns of the External Collaborators table:
  1. Date Added: format yyyy-mm
  2. External Collaborator(s): This is the person(people) approved by the ASE with the rights as outlined in the Apertif Participation and Data Usage Policy. Include their home institute.
  3. Title of project: any updates to the proposed title should be listed alongside the original title.
  4. Short Description: text longer than 50 words should be uploaded as a simple text file. Include link to the EC proposal (either PDF or Overleaf).
  5. Survey code: indicate on which survey the collaboration is primarily based (SNS/MDS/ARTS).
  6. Required data products: indicate what proprietary data products are required to undertake this project.
  7. EC sponsored students/postdocs: External collaborators may have associated students/postdocs: one student or postdoc per defined science project or paper.
  8. PhD Thesis: Y/N this column indicates whether the project will make up part of a PhD Thesis.
  9. Apertif Participant/Builder: This is the sponsoring member of the Apertif Science team.
  10. Status of project: this column must list one of the following indicators of the status of the project.
      • “active”: work is ongoing.
      • “closed”: work is complete.
  11. Publications: Use this column to indicate links to publications as a result of the EC. This should be updated upon the acceptance of a publication at the same time as the Apertif Publication Wiki.
  12. Notes: any other notes.

General instructions on editing and syntax can be found here. Text (.txt) or PDF (.pdf) files should be gzipped (due to wiki limitations) and uploaded in the wiki:ec namespace area (and coded as {{wiki:ec:myfilename.txt.gz}}.
