  • blue side cutoff due to glass dye; reasonably rapid cutoff
  • red side cutoff due to multi layer interference film
  • overall good efficiency
  • overall little ripple

  • Moro, D., & Munari, U., 2000, A&AS, 147, 361 (Paper I)
  • More than 100 photometric systems compared
  • Several hundred UBV ugriz etc systems
  • GIF plots
  • Text listings
  • Hot links to most of the original work
  • ADPS 2003: Fiorucci & Munari A&A 401 pp.781-796, Paper II
    • Parameters for all filters: various mean wavelengths, widths at 50% and 10%, asymmetries; synthetic photometry

conclusions
Conclusions
  • There are a variety of B band filter profiles
  • One has a large asymmetry towards the red
  • Most are nearly symmetrical
  • Best choice for SNAP needs to be explored
  • In our longest NIR passband, a redward extension is a serious contributor to our dark current owing to thermal tails of warm objects within our telescope
  • We should explore symmetrical passbands
