Summary

The following article should be used when you have issues with the DKIST DataCenter Data Portal. If you’re looking for help regarding Data Center User Tools not functioning, please go here.

Reasons, Solutions and Instructions

There could be a number of reasons why the DC Data Portal is not functioning. Please read through the list of possible reasons why you cannot find the data you’re looking for and assist the Help Desk in narrowing down the issue (by following the solution instructions below (in green)).

User’s computer is not connected to the internet

In order to search or download data using DC Data Portal, user must have internet connectivity to the DKIST Data Center to function.

Solution:

  • The DKIST Data Portal for searching and retrieving data is located at <http://dkist.data.nso.edu/>. There will be scheduled downtimes for the DC Portal for maintenance. During those times, a banner should be visible to the user noting the downtime. If the user receives an error stating that the search service is down and to try back later, please try again in a few minutes (to an hour).

    Ensure your internet connection is working fine. If link still does not work, in a separate tab, enter the search URL into http://www.isitdownrightnow.com. This should tell you if the downtime is expected.

    Please provide the following information to assist he Help Desk is tracking down the issue:

    1. Browser and version that you are using,

    2. Error message (screen shot)

Data requested (expected) is not available yet due to one of the following:

  • it is not processed yet by the Data Center

  • it is not available yet (sill being quality inspected during the Operations Commissioning Phase (OCP) only)

  • the Experiment hasn’t been run yet and therefore no data has been processed nor made available

  • the Experiment has been run, but the associated calibration data is not complete yet for pipeline processing

Solution:

  1. If you are the PI, you will get a notification when the data from your program(s) are processed, calibration and made available in the Data Center. Note that notifications regarding the status change of observing programs themselves being taken is not an indication that your data will be made available shortly thereafter; it can take weeks to complete the entire set of calibrations and data processing before the Data Center can release the Level 1 files.

  2. You will need to wait for these data to become available; please be patient.

  3. If none of the above matches your parameters, go to the next possibility.

Can’t request data for download even though it is available due to the following:

  1. The data you have selected are still under the proprietary period and cannot be downloaded; you will need to wait until this period ends and the data become public.

Solution:

2. The data you have selected are available, but there’s a problem.

Solution:

  • Please submit a Help Desk ticket

    1. Please provide details on what data you are looking for (i.e. Proposal ID, Experiment Completion Status Notification, DC Data Availability Notification, any other details to pin down the request)

There could be a user error with the search parameters sent to the Data Center:

  1. Problems with search parameters:

    1. user may not be searching correctly for data they want

    2. the search parameters may be too narrow, therefore excluding desired data

Solution:

  1. Double check the search parameters and ranges (See: How to on Search)

  2. Try to simplify your search

  3. Make sure you page through results if they are all not displayed on one page

  4. If you truly believe that your search is Ok, then please submit a Help Desk ticket with your search parameters

    1. Please provide details on what data you are looking for (i.e. Proposal ID, Experiment Completion Status Notification, DC Data Availability Notification, any other details to pin down the request)

See Data Center Archive data search results don't return my data for proposal X.

2. Correct data are being returned, but the number of results has been limited to 1000.

Solution:

  1. Be more specific in your search, for example use a smaller time range or add an extra filter.
