Observing with the Wide Field Spectrograph (WiFeS) – Version 1.3

This document provides an introduction to the Wide Field Spectrograph (WiFeS) instrument, its observing modes, capabilities and to the required calibration observations. It has been prepared by the project scientist, Emeritus Professor Michael Dopita. Any questions, comments or grouses should be addressed to: [email protected]. Sections 2–9 describing the instrument are adapted from the paper: Dopita, M.., Hart, J, McGregor, P., Oates, P & Jones, D. 2007, "The Wide Field Spectrograph (WiFeS)", Ap&SS, 310, 255. That paper must be referenced in any paper which has used observations obtained with the WiFeS instrument. Important Notice: During their observational run observers must not touch or alter any part of the instrument or its electrical connections. Failure to observe this notice may result in irreparable damage to the instrument. Observers must seek technical assistance in the case of any and all instrument problems.
