IFU: Arc Lines

Although UIST has Krypton and Argon lamps installed, at present only the latter is available for wavelength calibration (and the DR currently cannot handle arcs from the Krypton lamp). Plots of arclines for the UIST grisms are available from the Spectroscopy web pages. Note, however, that because spectra in alternate slices are shifted "left" and "right", in reduced data the ends of each spectrum are removed, so that approximately 5% is lost off the red and blue end of the wavelength coverage of each grism.
