NICMOS coronagraphic imaging capability is provided by a hole in the Camera 2 Field Divider Assembly which provides a 0.3 arcsec radius coronagraphic spot, with an effective useful radius of 0.4 arcsec at the detector image plane.
Coronograph users should read this important advisory for coronagraphic observing. Other important information on coronagraphy can be found in Chapter 5 of the NICMOS Data Handbook, section 5.1 of the NICMOS Instrument Handbook as well as in the following performance summaries: Performance of the Coronagraph in Cycle 7, and
