  22. 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 Lampton B-band filters
