Issue on reduced NIRPS data between April and July 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 tha ...

Release of “The MUSE View of the Sculptor” Programme

This data release presents a wide-field MUSE mosaic of the nearby starburst galaxy NGC 253 (the Sculptor Galaxy), covering its entire star-forming disc. The mosaic combines 103 individual MUSE pointings in Wide Field Mode, spanning 20 × 5 arcmin² and totaling approximately 25 hours of on-source exposure. Most of the observations (101 pointings) were obtained without adaptive optics (AO) using short exposures (~850 s), while the two ...

Archive User Interfaces: Abandoning the Request Handler

As of Monday 28^th of July 2025, the archive user interfaces will no longer offer the option to download data via the Request Handler. The Download Portal will remain the only choice available for web-access to archival data.

Scripts, including older versions of astroquery (before v 0.4.7), which use the Request Handler (search for string /rh/), won't be affected by this change, though please be aware that within the summer we will publish a new archive news explaining how to ...
