2023 Release of VLT/VLTI Instrument Data Reduction Software Packages

Published: 30 Mar 2023

The annual public release of ESO VLT/VLTI instruments data reduction software packages is scheduled for end of May 2023. Please note that the new pipeline packages will be released for the following operating systems: Fedora 34, 35, 36, 37; Scientific Linux 7; CentOS 7; macOS 11, 12, 13.

ESO is working toward full support for the Apple Silicon hardware, but for the time being it is not possible to say when MacPorts binary packages for the pipelines on such hardware will be provided. Nevertheless, the use of MacPorts is recommended as opposed to installing from install_esoreflex script. Although installations will take a bit longer than for those OS versions that are supported with binary packages, using MacPorts the pipelines will build and install from source in macOS running on Apple Silicon hardware. Users of operating systems for which no RPM or MacPorts packages are currently available can use the source kit installation as described in the online documentation.

In addition to the release of data reduction pipelines in May, some instruments with pipelines under active development have intermediate releases throughout the year. To get announcements of new pipeline releases, please send an e-mail or visit the VLT Instrument Pipelines webpage.
