Figure 7. no immediate plans to make IGRINS available next semes- ter. We do hope, however, to host IGRINS at Gemini again in the future, as well as other unique and compelling capa- bilities. Remember to keep an eye on future Gemini calls for proposals!

The team also will provide a simple data reduc- tion pipeline to assist novice users. At the moment, much work needs to be done to carry out the large number of planned 2018A observations and provide the data to the community — so there are Daniel Jaffe of UT Austin is the IGRINS Principal Investigator (PI). Chan Park of KASI is both deputy PI and KASI instru- ment PI. Jae-Joon Lee at KASI supervises the IGRINS opera- tional program on the Korean side. The IGRINS visit to Gemini is supported by the U.S. National Science Foundation under grant AST-1702267 (PI — Gregory Mace, UT Austin), and by the Ko- rean GMT Project of KASI. Further technical details are available in Yuk et al. (2010), Park et al. (2014), and Mace et al. (2016). — Alison Peck, Kimberly Sokal, and Hwihyun Kim Figure 8.

Lines resolved well below the slit width show that IGRINS optics for Gemini will perform as designed and sensitivity will be optimized. Figure 9.
