Scientific programmes which require a significant amount of observing time (300 ks) may be submitted as ``Large Programmes''. It is the responsibility of the Principal Investigator to flag a proposal as ``Large Programme'' within the electronic submission of the proposal with the RPS.
Some Large Programmes approved in previous AOs may have failed to achieve the original scientific goal due to enhanced background radiation and the PI may want to request additional observing time. In this case the proposal shall be flagged as ``resubmitted'' and identified as ``Large Programme'' type, regardless of the total time requested in the current AO.
Two OTAC panels will review each ``Large Programme'' with respect to the expected return for the scientific category. Each of the two panels independently recommends ``Large Programmes'' to the chairpersons meeting. Within the chairpersons meeting a session will be devoted to discuss and compare the recommended ``Large Programmes''.
OTAC can apply the ``Large Programmes'' procedure to every programme that asks for a significant amount of total observing time (300ks) if the scientific case is judged to be of scientific importance.
