5. Example 2 - J-band Longslit Point Source (111 l/mm grating)

In this example, we will reduce the GNIRS J-band longslit observation of a metal-poor M dwarf.

This observation uses the 111 l/mm grating, the short-blue camera, a 0.3 arcsec slit, and is set to a central wavelength of 1.22 m. The dither pattern is two consecutive ABBA sequences.
