Extention of Proprietary Data Period: While individual images of my target will have some value, the scientific goals of this program are possible only when the entire dataset has been collected. I am now requesting that the proprietary data period be set to run from the completion of the last visit in the set. The timing on this request is important since your answer will greatly impact the upcoming budget submission. Reply Requests for non-standard proprietary data periods are unusual and are granted only in exceptional circumstances. Such a request should be addressed to Duccio Macchetto as the Associate Director for Science Policy.
