host IGRINS at Gemini again
in the future, as well as other

observations with the help of Gemini staff
for a total of 50 nights (figures 8 and 9). The
team also will provide a simple data reduc-

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
