Spectroscopy

Several slits and Hartmann masks were installed. Tests (on stars, as well as using the Hartmann masks) of the internal focus show that there is no problem focusing the Wide Field camera on the slit, but that we may need to modify NOTCam in order to get the High Resolution camera in focus over the full NIR wavelength range.

A dummy grism was mounted and tested. A grism which allow separate J (5th order), H (4th order), and K (3rd order) observations with spectral resolution of $\sim$2500 for a 0.5 arcsec slit width using the Wide Field camera has been ordered.
