The NIRI Observing Tool Library appears in the list of science programs as "NIRI OT Library" and can be "fetched" in the same manner that a normal observing program is fetched. The library contains a wide range of example observing sequences using NIRI in imaging and spectroscopic modes, with and without AO. It also contains flat and arc calibration sequences and template observations of a large set of photometric standards (with coordinates).

It is highly recommended that the observers copy observing routines from the OT library into their programs and then modify them as needed. Observers should do this with each new program, as the sequences in the library may be modified from semester to semester.
