ISR 2024-03 : COS Lifetime Position 6 Enabling Summary
February 19, 2024K. Rowlands et al.
We summarize the activities performed to enable lifetime position 6 (LP6) for the Cosmic Origins Spectrograph (COS) instrument on the Hubble Space Telescope (HST). LP6 is located +6.5” above LP1. All G160M cenwaves were enabled at LP6, which became the default LP for G160M exposures on 2022 October 3, at the beginning of Cycle 30. This ISR presents an overview of the LP6 enabling programs, which includes target placement, focus sweep, and target acquisition enabling and verification.
