Cassini ISS narrowband filter transmission
System transmission functions for the NAC and WAC narrow-band filters. NAC filters are as follows: MT1, MT2, MT3 (purple: solid, dotted, and dashed); CB1, CB2, CB3 (green: solid, dotted, and dashed); and HAL (red). WAC filters are HAL (red), MT2, MT3 (purple: solid and dashed); CB2 and CB3 (green: solid and dashed). The geometric albedo of Titan is also given (solid black) to illustrate the placement of the methane band and continuum filters relative to the methane features in the spectrum of Titan.
