Mayall 4-meter Telescope Mosaic Ooff OIII+30nm k1015 Ooff OIII+30nm k1015 Note that there is a shift in central wavelength when placed in different f/ratio beams. At the KPNO 4meter f/3.1 beam this corresponds to a shift of approximately 12 Angstroms bluer; at the CTIO 4meter f/2.9 this corresponds to a shift of approximately 15 Angstroms bluer; at the WIYN 0.9m f/7.9 this corresponds to a shift of approximately 5 Angstroms redder. See the plot at the bottom of the page.
