OSIRIS Data Processing and Products Correction

In April 2015 it was discovered that due to a defect in the software, some of the reduced data products for OSIRIS were being mixed in with the raw data as part of the ingestion process. Sixty-five nights of OSIRIS data were affected and had to be reprocessed and reingested into the archive. The reprocessing is now complete, and the issue has been resolved within three weeks of discovery.

If you downloaded data from any of the following nights before April 2015, we recommend you re-download the data to obtain the corrected version.

Reprocessed OSIRIS nights include:
