|---|---|---|---|---|---|---|---|
| M2030 | Gemini South | Phoenix | M2030 | Start (cm-1 μm): 1980=5.050 - Stop (cm-1 μm): 2080=4.808 - Echelle order 11 | |||

| M Washington k1007 | 1140.00 | 5100.00 | Nicholas U. Mayall 4-meter Telescope | Mosaic | M Washington k1007 | M Washington k1007 | 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. See plot at the bottom of the page. |
| M Washington k1007 | Nicholas U. Mayall 4-meter Telescope | Mosaic | M Washington k1007 | M Washington k1007 | Below is a plot of the transmission of this filter when used at telescopes with differing focal ratios and central obscurations; the KPNO 4m (f/3.1), the CTIO 4m (f/2.9), and the WIYN 0.9m (f/7.9). At the KPNO 4m f/3.1 the properties of this filter are: CWL=5168A, FWHM=1126A, PEAK TRANSMISSION=86.5%. | ||
| M Washington c6007 | 1020.00 | 5020.00 | Nicholas U. Mayall 4-meter Telescope | Mosaic | M Washington c6007 | M Washington c6007 | Note: The central wavelength of CTIO Mosaic narrow band filters (actually all filters, but is very significant for narrow band filters) is shifted ~15A to the BLUE in the f/2.87 beam of the Blanco 4m + PFADC corrector as compared to the transmission measured in parallel light. The central wavelength quoted below is nominally for when the filter is used at PF, with the ~15A shift included. Furthermore, the filter transmission curve presented below shows the simulated filter transmission curve for the Blanco 4m + PFADC f/2.87 beam. |
