Filter FWHM (Å) CWL (Å) Telescope Instrument Plot Data Comments
z SDSS k1020 *** Retired! 2000.00 9400.00 Nicholas U. Mayall 4-meter Telescope Mosaic z SDSS k1020 *** Retired! z SDSS k1020 *** Retired! NOTE: This filter was damaged in June 2011 and is retired. The CTIO SDSS z' filter (c6020) can be requested as a replacement, but it's availability will depend on demand at CTIO. 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 bluer.
