InstOps team

Accomplishments

• Met with Raytheon RTX on the continuation of the contract for delivery of short-wave IR sensors and future production of mid-wave IR sensors.

• Restarted all instrumentation.

• Tested Cryo-NIRSP context imager controller issue.

• Performed GOS testing of DL focus and alignment.

• Tested deployment of HLS Pono 8 release.

• Repaired GOS occulter controller.

Data Center team

Accomplishments

•  Began writing on the DKIST DC Cybersecurity incident Response Plan. This document will define how DC personnel will respond when/if a security incident occurs.

• Flipped the spatial axes in the L1  DL-NIRSP  data generated by the current DL-NIRSP pipeline.  The DL team had indicated that the current 3D cubes were rotated by 90 degrees in the spatial dimensions.

• Fixed the gain issues in the DL-NIRSP pipeline. Preliminary tests of real DL-NIRSP data indicated that the gain correction was not being correctly computed and applied.
