The paper by van Dokkum & Conroy (2011) (ApJL 735, 13) indicates that the Gemini web-site contains a template for the Mauna Kea night sky. Does anyone know where to find this? I haven’t had any luck.
More generally, what strategies would people recommend for correcting GMOS long-slit spectra for telluric absorption? Would it make sense to flux calibrate one’s data first and then correct for this absorption of the other way around?
