Summary
The DKIST Data Center Archive (DC) provides calibrated (a.k.a. Level 1, “L1”) data to the community via the User Portal for download. It does not generally provide general access to raw (a.k.a. Level 0, “L0”) data. However, special requests can be made using a request form to the DC for raw data files for certain instruments. If the user has a justified reason to get these raw data, they can make a request to the DC for access. Requests will be reviewed on a case by case basis. It is assumed that a user will already have downloaded the L1 data before requesting the raw data. You are required to specify the dataset IDs from the L1 data that corresponds to the raw data you wish to download. Raw data is not searchable and cannot be filtered by instrument or other similar parameters. If the request is approved, the user will receive ALL the raw data for at least one observing program as executed at the telescope.

Nearly all Please note that VBI raw data isspeckle reconstructed and this data is then transferred to the data center. In such cases unreconstructed VBI data will not be available. If you requested unreconstructed data in your proposal, then this data will still have gain and dark corrections applied. If you are going to need unreconstructed VBI data, you must request it in your proposalNOT available for request at this time. |
