NOTICE: We recently discovered that calibration information was incorrectly applied to a number of instrumented systems data products (list of affected products below) from Feb 26, 2018 to present. All potentially affected data have been removed from the data portal and will be reprocessed with appropriate calibration information. Reprocessing should occur throughout February. Data will be published as it is reprocessed. The error resulted from a manual database procedure that updated calibrations after a sensor change. We are automating this procedure to avoid this problem as we transition to a fully operational observatory in the near future.

We apologize for any inconvenience this may cause. For more information, please read the full announcement
