Observations requested through Director’s Discretionary Time (DDT) typically have a proprietary period of three months. PIs may also choose to waive the proprietary period.
Open Time proposals typically have a proprietary period of 12 months after the last observation has been obtained.
Proprietary periods vary for Large Survey Projects (LSPs) depending on observing seasons.
Tape Storage
Note that due to disk storage constraints, data will be moved off active disk storage to tape after six months. Restaging data to disk is possible but may be subject to significant delays. You are therefore advised to initiate transfer of your data as soon as possible.
Due to the large volume of a typical imaging dataset, and the need to convert from MVF to MS format the download link will take up to 2 weeks to generate.
