The document named "CFIS Data Access and Collaboration: Rules & Guidelines" was created and is maintained by the
Canada-France Imaging Survey (CFIS) PIs and the CFIS Steering Group, with further input from the CFIS Collaboration
at large upon the initial consultation. It was drafted in consultation with the SAC chair, the CFHT head of science
operations, and the CADC lead. The document will remain open for modifications over the course of the collaboration
lifespan to adapt to unforeseen conditions.
Accessing the CFIS standard products outside of the CFIS Collaboration means endorsing the relevant rules described below
(from Section 1 of the document).
Accepting to be part of the CFIS Collaboration and accessing the CFIS core and advanced products from the collaboration
means endorsing all the rules and guidelines found in the document. Since there are more than 110 collaborators in the
CFIS Collaboration and the final dataset is large and unique, it is indeed necessary to have a set of high level rules
to ensure the smooth running of the collaboration. The spirit of this document is to maximize communication across the
collaboration and minimize top down management, while ensuring the collaboration members are appropriately credited for
work and results stemming from the CFIS dataset. In summary, the collaboration document describes the nature, organisation,
management, and collaborative principles of the CFIS. The document is publicly accessible through the following link:

Standard data set: access for C&F users not in the CFIS Collaboration
|
- The CFIS standard data that are openly available to all members of the C&F communities (scientists based in C&F institutions) consist of the regular CFHT MegaCam products: raw data and the individual detrended images by CFHT (Elixir). Access by any member of the C&F community (including those in the CFIS Collaboration) to this standard dataset at CADC implies registration through CFHT. To do so, interested scientists must email the alias <cfis-cf at cfht.hawaii.edu>, using their home institution email and including "CFIS registration" in the subject line. The message must include an endorsement of the specific rules defined in this section 1 of the present "CFIS Data Access & Collaboration: Rules & Guidelines" document.
- The raw and detrended images are proprietary within the C&F communities up to August 1, 2023, and thereafter released globally by CADC in the usual way.
- CFIS C&F registered users agree to protect the proprietary rights of the Canadian & French community by not exporting proprietary images to persons other than CFIS C&F registered standard users, or by making public the data in digital form.
- Once the standard proprietary CFIS data have been processed to the point of published scientific analysis, these advanced measurements can be shared with non C&F communities as part of a pointed science collaboration. Publication implies documented analysis procedures and a scientific analysis that peer review accepts. The bulk of the intellectual effort in producing the advanced products must reside in the C&F communities, such that they are not just the result of running a non-C&F code in a C&F institution. The CFIS PIs must be consulted when anticipating such arrangements.
- Users of CFIS standard data should include an acknowledgement in all publications as follows (with the standard CFHT-MegaCam acknowledgement text) :

This work is based on data obtained as part of the Canada-France Imaging Survey, a CFHT
large program of the National Research Council of Canada and the French Centre National
de la Recherche Scientifique.
Based on observations obtained with MegaPrime/MegaCam, a joint project of CFHT and CEA Saclay,
at the Canada-France-Hawaii Telescope (CFHT) which is operated by the National Research Council
(NRC) of Canada, the Institut National des Science de l'Univers of the Centre National de la
Recherche Scientifique (CNRS) of France, and the University of Hawaii.

Advanced data set access and joining the CFIS Collaboration
|
- The rest of the Rules and Guidelines presented in the document pertain exclusively to the CFIS Collaboration and its own products as described in the document.
- All members of the C&F community (scientists based in C&F institutions) are welcome into the CFIS Collaboration as long as they commit to the rules and guidelines of this whole document. Interested scientists who did not sign the original proposal ought to contact the CFIS PIs via email (using their home institution email) with a brief description of their interests and anticipated involvement in the CFIS.
