F25ND3—NUV-MAMA
Description
The F25ND3 mode with the NUV-MAMA provides broad band imaging with an attenuation of 10-3. The value of R80 and the central pixel flux are unmeasured but assumed to be approximately the same as produced by the F25QTZ filter.
Recommended Uses
Recommended for broad-band NUV imaging of objects too bright by 103 for clear mode.
