Issue on reduced NIRPS data for observations between 2025-04-01 and 2025-07-24

Published: 10 Sep 2025

NIRPS data for observations between 2025-04-01 12:00 and 2025-07-24 12:00, reduced with the pipeline version 3.2.6, have been affected by a technical issue impacting the accuracy of the radial velocity. For science cases requiring a precision better than 10 m/s, those data should not be used. We strongly advise (re-) downloading the updated Phase 3 data, which have been reprocessed with the pipeline version 3.2.7 (refer to the PROCSOFT FITS keyword).

Also, please beware that the QC0.NIRPS quick-looks in that period have not been reprocessed and remain affected by this issue.

We apologize for any inconvenience this may cause and thank you for your understanding.
