Left: The HWO OS1 ConOps uses a reference star for wavefront sensing to expedite the wavefront control sequence. Center: After the dark hole is created, the observatory is slewed to a science target with an angular roll of +22◦, waits for stabilization, and then an imaging sequence is executed. Right: The observatory is rolled to −22◦, a 40◦ roll in total, waits for stabilization, and then an imaging sequence is executed. Subsequent rolls and periodic wavefront control maintenance visits to the reference star complete the observing scenario. Simulated data based on HWO integrated modeling results provided by John Krist. -- astro-ph.IM
