Overview of Instrumentation at INGThis page provides an overview of the instrumentation at the WHT and INT. Further information about a given instrument can be obtained by clicking on the instrument name, or by emailing one of the listed instrument specialists. At the INT, the usual instruments (IDS, WFC) are offered in 2023B, and may be available during a fraction of 2024A as well. At the WHT, commissioning of the new multi-object spectrograph WEAVE, is in progress. As of May 2023, the LIFU (large integral field unit) mode is commissioned, with science-verification observations have started. The LIFU mode is being offered for open-time observations in 2023B. Once the MOS and mIFU modes of WEAVE have also been commissioned (by ~ mid-2023, if all goes well) a long-term average of 70% of the time at the WHT will be devoted to the WEAVE surveys. The remaining 30% of the time will be available for 'open time' community observing with WEAVE, with the Cassegrain instruments (ISIS, LIRIS, ACAM) or with visiting instruments. Open time for the MOS and mIFU modes of WEAVE will only be advertised once they are commissioned. It's expected that WEAVE will stay on the telescope during all of 2023 and 2024, so non-WEAVE open time will not be offered during this period. The latest news about the ongoing evolution of the instrumentation at the WHT and INT (following a 2014 poll of the community) can be found on the ING instrumentation update page. Information about how to apply for telescope time can be found on the applying for telescope time page. Notes (§) about specific instruments and procedures can be found at the bottom of this page. Information about instruments no longer offered at ING (e.g. the multi-object spectrograph AF2) can be found on the page about past, present and future instruments. |
