Simulations and preliminary bench data show LDFC and EKF dark zone maintenance can stabilize vortex coronagraph contrast on the SCoOB testbed, with LDFC failing on low-order testbed drift.

The Space Coronagraph Optical Bench (SCoOB): X. Dark zone maintenance
Simulations and preliminary bench data show LDFC and EKF dark zone maintenance can stabilize vortex coronagraph contrast on the SCoOB testbed, with LDFC failing on low-order testbed drift.
