Characterisation of the Optical Turbulence at Siding Spring

Michael Goodwin, Charles Jenkins, Andrew Lambert

Measurements of the optical turbulence profile above Siding Spring Observatory were conducted during 2005 and 2006. This effort was largely motivated by the need to predict the sta…

Laser frequency comb techniques for precise astronomical spectroscopy

Michael T. Murphy, Clayton R. Locke, Philip S. Light +2

Precise astronomical spectroscopic analyses routinely assume that individual pixels in charge-coupled devices (CCDs) have uniform sensitivity to photons. Intra-pixel sensitivity (I…
