F25ND3-NUV-MAMA
Description
The F25ND3
mode with the NUV-MAMA provides broad band imaging with an attenuation of 10-3. The field of view is 25 x 25 arcsec. The R80 and central pixel flux are unmeasured but assumed to be approximately the same as produced by the F25QTZ
filter.
Recommended Uses
Recommended for broad-band near-UV imaging of objects too bright by 103for clear mode.
