NOAO Time on WIYN in Semester 2019A
NOAO will continue to offer access to WIYN and its instruments to the national community in 2019A, albeit with a focus on research programs that are related to exoplanets. Interested observers should consult the NOAO WIYN 2019A Observing Proposal Call for details. This does not apply to people applying for time through WIYN's university partners.
Instrument availability in 2019A
There are several key things to note about the availability of 3.5-m instruments in 2019A:
- ODI: WIYN has procured four full-sized narrow-band filters for use by observers; NB422, NB695 (red-shifted H-alpha), NB746 (red-shifted H-alpha), and an H-alpha filter. We will no longer be supporting the use of Mosaic filters with ODI in 2019A.
Additionally, flat-fielding is now done as a service to observers by observatory staff. Contact Wilson Liu for more information.
- All other WIYN instruments besides ODI share the second Nasmyth port, known as the Hydra port. Thus, (the IFUs)+WHIRC, WHIRC+Visitor Instruments, and Hydra will be block scheduled. The switch between Hydra and the Instrument Adapter System (IAS) that supports the WIYN High-Resolution Infrared Camera (WHIRC), SparsePak, Hexpak, Gradpak, NESSI, and visitor instruments takes two to four days to complete. Normally there is one change from Hydra to the IAS and another switch back to Hydra each semester.
- The two new unique IFUs, HexPak and GradPak, will continue to be offered for shared-risk observing in 2019A. These IFUs are distinguished by having different sized fibers in the same head to optimize the balance between surface brightness and signal-to-noise for various classes of extended objects. They were developed by Matt Bershady's group in Washburn Astronomical Laboratories at the University of Wisconsin-Madison. As they are still PI-level, rather than facility, instruments, it is necessary to work with the PI before submitting a proposal to use the new IFUs. Please read the introduction letters from the WIYN director and the instrument PI. More information and instructions on how to proceed can be found on the Hexpak and Gradpak web pages. SparsePak will continue to be offered as a facility instrument.
- WHIRC will continue to be offered. See the WHIRC Hot News for the latest updates.
- The queue-operated speckle imager NESSI (NN-Explore Exoplanet Stellar Speckle Imager) will be offered again this semester.
Remote observing at WIYN is available to all qualified observers (see the remote observing policies). Those wishing to observe remotely with ODI must do so from a pre-approved (and tested) workstation. More information can be found on the WIYN Remote Observing page.
