  • 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
