Euclid Tracking Page i.e. Becoming a Member of the EC (or tracking.euclid-ec.org)

This page is the main and most current list of EC members. In order to be added to the list and gain access, you must:

  1. fill in this form, and
  2. email your country representative (see list on this page). Note that if you are looking to work in the SGS, you should cc “Andrea Zacchei” in your email to the country rep.
    For more, developers should also see the Start Guide issued by the SGS (ESA Cosmos login required).

The Tracking Page will then ask you every 6 months to log your work on Euclid in order to assign you a membership status (Contributing Member, Long-term Contributor, Builder, Founder), which entitles you to signing different EC publications on the Euclid Consortium Editorial Board (ECEB) portal (see below).
If you are already on ESA’s list of EC members (see below), follow the Lost password procedure to gain access to the Tracking Page.
For technical help, contact Simon Berquez (Frederic Magnard & Thierry Maciaszek might have access too).
This page is managed in France by the EC Lead Support Office.

ESA Cosmos and the Cosmos Wiki

This page uses ESA’s list of EC members (we are currently trying to unify this list with the above list from the Tracking Page, which is currently a manual process). This is the page that provides several other portals with login credentials, so it is important to gain access here too.
A ticket will be submitted on your behalf (at the Euclid Cosmos Helpdesk) when your Euclid Consortium membership is approved.

For help, contact Oriana Mansutti & John Hoar.
This resource is managed by ESA.

Euclid Redmine (or redmine.euclid-ec.org)

This page is used heavily by many groups in the EC for project management and for wikis.
You can gain access by:

  • filling out this form – note that you should use you professional email in the registration form, since personal emails, like gmail, will not be validated; note also that the handle you choose should be your Cosmos account username (if you don’t have one yet, see above), and
  • emailing Keith Noddle & Rob Blake, cc-ing your ECB rep who will confirm that you have been approved for EC membership. Make sure you let them know whom you work with and what you work on (so that they can give you access to the correct science working groups – SWGs, organisational units – OUs etc.).

Once you have access to the Redmine, you can view a list of Euclid acronyms (which is probably not the only one and possibly not complete, but it helps).
For help, contact Keith Noddle & Rob Blake.
This resource is managed in Scotland, by SDC UK.

Public-facing, googlable EC page (here: www.euclid-ec.org)

You are here now.

For help, contact Simon Berquez or Francis Bernardeau (Frederic Magnard & Yannick Mellier have access too).
This page is managed in France by the EC Lead Support Office.

Projects Portal (or: projects.euclid-ec.org)

This is a portal built to manage Euclid projects (not the Projects Page on the Redmine!). It contains a list of the major entities in the EC (like the SWGs and OUs) as managed groups. The smaller work packages (WPs) are listed as projects that can be managed by their leads once approved. Similarly Euclid Key and Standard Projects can be managed the same way. Currently the main use of the PP are the project and group mailing lists. It may be discontinued in the near future.

To gain access you should follow the instructions. In short:

  • make sure you are an EC member and have access to the Tracking Page,
  • (optional) make sure you have ESA LDAP credentials (you have them, if you have access to the Cosmos Wiki above for example), and
  • follow the Forgot password procedure in the “Local (for guests)” tab.

For help, contact Jascha Schewtschenko & Patrick Simon.

This page is managed in the UK and Germany by the ECEB.

GitLab (or: gitlab.euclid-ec.org)

This is where the code development happens. It is the internal, Euclid Consortium GitLab (similar to GitHub, but not public).
If you have access to the Cosmos Wiki above, you should be able to:

  • use those credentials to log in on the “Esac-LDAP” tab.

For help, email Rob Blake & Matthieu Marseille.

This resource is managed in Scotland by SDC UK.

Euclid Consortium Editorial Board (ECEB) page (or pubs.euclid-ec.org)

This is a simple, but useful page that keeps track of official Euclid publications, manages the internal review process, and allows members to sign papers they didn’t directly work on in the case they have earned their right to do so by significantly contributing to the project.
To access it you can use the universal credentials for this page, which are shared by the whole collaboration:

  • Obtain the universal login credentials on the ECEB Redmine wiki or, if you don’t yet have access to the Redmine, from an EC colleague. Please do not share this outside the EC.
  • Whenever a new publication is submitted you will receive an email, once you are listed as a member on the Tracking Page.

For help, contact Patrick Simon & Jascha Schewtschenko (Ole Marggraf has access too).

This page is managed in Germany, by the ECEB.

These are the ESA-hosted Euclid pages. Livelink / OpenText in particular is a document management system that is used to store official Euclid documentation. Each member has access to all EC-specific parts of it, but some documentation that is confidential cannot be found here (that lives on an ESA part of Livelink or on the Eclipse, where the access is managed strictly).
To find the documents

  • follow the above link,
  • sign in (Livelink is ESA-hosted so uses the same credentials as the Cosmos Wiki),
  • go to Tools -> Livelink, and
  • sign in again (top-right).

For help, contact John Hoar & Oriana Mansutti.

This page is managed in Spain, by ESA.

SGS Documentation

To get an overview of all the Science Ground Segment (SGS) documents, you may rather take a look at the list on Cosmos (login required). Don’t be discouraged by error messages when following links – just log in and try to follow the link again. Here is a diagram of how these documents are connected and the types of documentation in the SGS. If you intend to prepare SGS documentation, see the guidelines on the Cosmos Wiki.
There is a lot more to Euclid SGS documentation than belongs into a QuickStart Guide. For help on this topic, please contact Oriana Mansutti.

Slack (soon: slack.euclid-ec.org)

We have a licensed workspace in the EC. All EC members should receive invitations once they appear as an active member in the Tracking Portal. Please attempt to log in at euclidconsortium.slack.com with your Tracking Portal email. For help, please submit a Redmine issue in the Slack space, if you don’t have access to the Redmine, send email our EC portals support team and note that EC Slack leads are currently Jennifer Pollack and Dida Markovic.

Note that there are still many Slack workspaces that are in use in the Euclid Consortium. We are currently working on consolidating all of them into the one and only workspace above.

Actually finding out what people are doing

Having access to all these resources doesn’t guarantee that you will find what you are looking for. Once you have access to most of these (or while you are waiting for it) look at this list of group leads. The best would be if you select one group you’d like to join, contact its leads (see list) and ask them:
where they keep their work (for example, they may document their WPs on the Redmine, so they should make sure you have access to it), and
how do they communicate (when the main telecon is, how to sign up for mailing lists, is there a Slack/Discord workspace that you can join…).
When you have access to the group’s main space, you can find what specific WPs there are and join what you are interested in, again mostly by contacting their leads and asking similar questions as above.
For this you will probably be using some combination of the following, widely available tools for virtual work: Google Docs (Slides, etc), Overleaf, Dropbox, Slack, Discord, Zoom, Webex, Skype, Google Hangouts…

Other pages and portals

The above are the main portals, but you may find it useful to access some of the following sites sometimes too:

  • CosmoHub – not an official EC portal, but it hosts several cosmological simulations that were designed especially for Euclid.
  • the Mission Database (public and out of date or not accessible to the majority of the EC)
  • US help pages
  • European help pages
  • PBworks
  • the Euclid Archive
