Preparing for WINERED observations at LCO
The WINERED is open to use by general users who have access to the Magellan telescope time. Please check the Information on the WINERED with Magellan for 2024A for planning observations in the 2024A semester.
Please find here the information on observations with the WINERED attached to the 6.5-m Magellan Telescope (Clay) at LCO, Chile.
How to use the WINERED for your science
This lists a typical sequence of the steps for using the WINERED.
- Find the specification of WINERED at our web site or more details in the instrument paper (Ikeda et al. 2022).
- Think what can be done with the WINERED. The Exposure Time Calculator (ETC) is available.
- Check the status update for the semester, together with the call for proposals from your relevant TAC.
- Submit your proposal to the TAC through which you can get access to the Magellan telescope time.
- Check the agreement with the WINERED team concerning the use of WINERED.
- Once your proposal is awarded the time, contact the WINERED team via e-mail and start to discuss your observations with us. Sending your proposal to us would be most simple, or at least we need to know the technical justification of your observations.
- Decide who will observe at the LCO (or remotely, if necessary): you, your collaborator, or some other delegate?
- Prepare the Observing Catalogs necessary for the telescope operation. It will be handled by the telescope operator. WINERED can get the target information from the telescope and include it in the FITS files.
- Conduct the observations (some of us will be at the site at every observing run to assist all the WINERED observations).
- Use the WINERED data for your science. Check the page on Data and Analysis.
- Make the acknowledgement when you publish results obtained with the WINERED.

Observation
We request each program send an observer (or observers) to the Las Campanas Observatory in order to conduct the operation of WINERED by themselves. The WINERED team will be at the observatory to support the observer(s) by giving instructions on the operation to unfamiliar observers and by trying to solve instrumental troubles.

Semesters
- LCO Telescope Schedule - Calendar, 2024
- 2022A — We could visit the LCO from Japan/US and a commissioning run was allocated.
- Engineering run was held in July. We re-assembled the WINERED and checked its performance (including the IR detector) at the laboratory space in the ASB (Astronomers Support Building).
- LCO22a — 4 nights (July 16-19) were allocated. We set up everything in the ASB, but the heavy snow prevented us from bringing the WINERED to the telescope dome (Clay).
- 2022B — A scientific run was held although WINERED was not open in the calls-for-proposals.
- LCO22b (report) — 5 nights (September 12-16) were allocated, and we successfully made the first light of the WINERED attached to the Magellan telescope (Clay).
- 2023A (preparation)
- LCO23a (report) — 11 nights are allocated in June.
- 2023B (preparation)
- LCO23b (report) — 15 nights are allocated in October/November.
- 2024A (preparation)
- LCO24a (report) — 13 nights are allocated in April.
- 2024B — The WINERED will be open in the calls-for-proposals.
Agreement required before the proposal submission
The WINERED is a high-resolution specrograph covering 0.9—1.35 μm
(Ikeda et al. 2022),
which is currently a PI instrument available at the Magellan 6.5-m telescope (Clay).
It is going to be available to each person who has access to the Magellan telescope time,
but an agreement should be made
with the WINERED team before the proposal is submitted.
The agreement would include that 20 percent (by default) of the allocated time
would be used by the WINERED team for their own observations.
Please check the agreement described at the following page:
Acknowledgement
In your papers, please cite Ikeda et al. 2022 and include the following acknowledgement.
This paper includes the WINERED data gathered with the 6.5 meter Magellan Telescope located at Las Campanas Observatory, Chile.
Also, in your press releases, please give an explanation of the WINERED like follows (besides the acknowledgement to the Magellan telescope and the Las Campanas Observatory).
The data used for this research were (partly) obtained with the WINERED near-infrared spectrograph,
which was constructed and operated by the Japanese team from Kyoto Sangyo University and the University of Tokyo.
