F25ND3—FUV-MAMA

Description

The F25ND3 mode with the FUV-MAMA detector provides broad band imaging with an attenuation of 10-3. The field of view is 25x25 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 imaging of bright objects requiring 10-3 attenuation to meet FUV-MAMA bright object protection limits.
