Web2 days ago · Selection of bandpasses. The temperature classification of early-type stars is based on Balmer jump (Balmer discontinuity). To measure it one must have two bandpasses placed in the ultraviolet, one beyond the Balmer jump (U magnitude) and another after the jump (X magnitude).. The Y bandpass is near the breakpoint of the … WebThese filters are used to select particular bandpasses. They may be made of a combination of long- and short-pass filters. Narrow band filters are generally interference filters. Common bands include: Broad bands These representative glass combinations are those used at the Palomar Observatory 60" telescope. The Johnson U,B,V bands are … garaway high school address
