Download ascii data for filters:

  • u: Effective central wavelength 349.6nm, FWHM 23.8nm
  • v: Effective central wavelength 410.3nm, FWHM 15.7nm
  • b: Effective central wavelength 466.6nm, FWHM 15.6nm
  • y: Effective central wavelength 550.5nm, FWHM 18.6nm

(effective central wavelength & FWHM: filter transmission mimics a 100% at ECW@FWHM)

 

H-beta: narrow & wide, FWHM 3nm and 13nm
