Only registered individuals have access to the proprietary SLS data. The eligibility of individuals to receive proprietary access to the SLS data includes:

• all persons engaged in astronomical research residing in France, Canada, Hawaii, Brazil and Taiwan (as long as these countries are CFHT partners and agree to contribute to the SLS) - including students, post-doctoral fellows and employed professional astronomers at Universities and Research Institutes (persons from IfA/UH may also be eligible if IfA/UH chooses to bring an additional ~90 nights to the full SLS survey time);
• members of the CFHT scientific staff;
• professional astronomers employed at Research Institutes or Universities outside of Canada or France, but who are directly or indirectly supported by either NRC or CNRS, or another French or Canadian agency (e.g., a French Astronomer at ESO, a Canadian astronomer at JAC).
• individuals who do not fit the stated eligibility criteria but nevertheless believe they may be eligible to be included in the SLS community may apply for authorization to register, stating their argument, to the SLS-EB and the CFHT executive director.

Previously registered users whose status changes to one that no longer fits the stated eligibility criteria will normally be removed from the list of authorized users (their registration will be revoked). Such individuals may appeal to the SLS-EB and the CFHT Executive Director, stating their reasons to continue as a registered user of the SLS.

The CFHT Executive Director is charged with administering a system of registering eligible persons to become users of the SLS data. The registration form will contain a statement of the obligations associated with access to the data, especially regarding the SLS Data Access Policy including the proprietary nature of the data, and the SLS Publication Policy.
