Notes. “JH” in the slit width column refers to observations where a K-band blocking filter has been used. The seeing is determined from the width of the spectral trace of a telluric standard star, observed close in time to the host observation. The spectral resolution, R, is measured from unresolved telluric absorption lines in the spectrum of the telluric standard star.
