Information on the WINERED with Magellan for 2023B
Observing Slot(s)
WINERED (risk-shared) will be open to the Magellan users. Since we need to send a team from Japan to operate the WINERED, PI instrument, we would be able to have only one or two runs in each semester. For the 2023B semester, please consider observations in the following slot(s):
- To be confirmed
- Currently we are not sure whether we would be able to have two observing runs within the 2023B semester. We encourage proposals for making observations between late August and early November, but we may limit the period during which we can support the observations. Please check this page before the deadline and feel free to contact us on the schedule and other things.
Proposal Preparation
- Check the call for proposals. For example, here is the call by the Carnegie TAC, but you should check the one through which you can apply for the telescope time.
- Check How to use the WINERED for your science
- Check the expected agreement with the WINERED team.
- Some documentations on the WINERED required.
- If you have questions, please contact us.
- Prepare and submit your proposal to the TAC you have access.
- For each proposal submitted, please send the information on your proposal via the WINERED Proposal Information Form (being prepared).
(Please don't forget this!)
WINERED Status
- We expect the WINERED is fully operational in the 2023B semester.
- We made the first light with the WIDE mode of the WINERED
at the Magellan telescope (Clay) in 2022 September, and expecting 11 nights in 2023 June.
- Report on the first light in 2022B:
- Gnerally speaking, the WINERED co-works with the telescope well and we can obtain high-quality spectra, as expected, although the sensitivity and the efficiency may be lower under some conditions.
- The differential refraction lowers the slit throughput when the target's altitude is lower than 45 degrees. The loss is especially significant in the J band when the target is put into the slit on the slit viewer.
- Introducing the target into the slit and tracking it was sometimes inaccurate, which could have lowered the sensitivity by 20-30 percent. We are working to improve this by modifying the algorithm and software in the next semester.
- For planning observations in the 2023B semester,
please use the correction factor (cor_factor) of 0.8 for targets to be observed at high altitudes
or 0.6 for targets at low altitude (< 45°) to be conservative.
