An individual LLP need not request a balanced program across North/South, RA range, observing conditions, etc. However, the ensemble of approved LLPs must not overly impinge on other observing programs. Therefore, the ensemble of approved LPs should not exceed ~25% of any relevant parameter, such as hemisphere, RA range, and observing condition bins. See this page for further information on observing condition constraints.
LLPs will also be subject to general semester target availability restrictions, as published in the general call for proposals for each semester.
The instruments available for new LLPs are listed below, along with any particular restrictions of note. Successful LLPs may also be limited by the semester-specific instrument availability restrictions announced with each semesters regular Call for Proposals.
