The observing time allocation guaranteed under AO 01-OSS-05 and NASA-ESA-CSA agreements may be redistributed or combined internally among the selected PIs and scientists by mutual agreement of those affected and the concurrence of the STScI Director and NASA HQ. These concurrences are needed, since such redistribution may affect the planning and scheduling activities of the STScI. Observing time redistribution may not alter the total guaranteed time allocation nor the formula describing its overall distribution in the JWST AO (and thereby does not impact General Observers in any way).
