We have a UBVRI filter set which consists of the following:
U: liquid CuSO4 + UG1 [42-inch has UG2]
B: not: 1mm BG12 + 2mm BG39 + 1mm GG385
V: 2mm GG495 + 2mm BG39
R: 2mm OG570 + 2mm KG3
I: Interference filter.
We have traced these filters on the Lambda 9 spectrophotometer of NOAO, and provide both the plots and the data files below. In addition, we compare the filter curves convolved with our CCD DQEs with the standard system:
| Bandpass | Filter tracings | Comparison with Standard System | |
|---|---|---|---|
| U: CuSO4+UG1 (72-inch) | Plot | Data | Plot |
| U: CuSO4+UG2 (42-inch) | Plot | Data | Plot |
| B | Plot | Data | Plot |
| V | Plot | Data | Plot |
| R | Plot | Data | Plot |
| I | Plot | Data | Plot |
