Space Telescope Science Institute  25MAMA-FUV-MAMA Clear F25ND5-FUV-MAMA

F25ND3-FUV-MAMA

Description

The F25ND3mode with the FUV-MAMA detector 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 imaging of bright objects requiring 10-3 attenuation to meet FUV-MAMA bright-object protection limits.
