The SLS is based on the concept that all members of the SLS science consortium have equal access to the raw and reduced SLS data obtained at the CFHT and archived at CADC. Access to the SLS data require SLS members to first obtain registered status. The raw and reduced data are made available at CADC to all registered users at the end of each SLS run through a password-protected archive.

The processed data include both the non-telluric-subtracted and telluric-subtracted spectra with wavelengths referring to the Solar-System Barycentric frame, and corrected from all known residual instrumental contributions to the RV signal. RV measurements and Zeeman signatures derived from processed spectra with reference cross-correlation tools are also released with the processed spectra.

The raw and processed data released by CADC are proprietary within the SLS for a period of 12 months after the end of the SLS for the SLS components that require analyzing the whole sample, or 12 months after the end of the semester in which the last data of a given homogeneous subsample are collected for components that do not intend to exploit the whole sample at once (eg for the transit observations of WP2).

Registered users commit to protect the proprietary rights of the SLS community by individually not exporting / showing proprietary data to scientists other than registered users, nor distributing the data in digital form. The export of SLS proprietary data to external members of the SLS science consortium is permitted only upon the explicit authorization of the SLS executive board. Failing to comply to this policy will imply exclusion of the SLS consortium.
