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
NICMOS Coronagraphy Documentation
Important updates, discoveries and developments that could potentially affect NICMOS observations, calibration, or data analysis.
Status reports reflecting the current understanding of instrument characteristics, performance and calibration.
The NICMOS Instrument Handbook is the primary guide regarding the characteristics and use of the instrument. The HST Data Handbook is the primary guide for calibration, reduction and analysis of NICMOS data.
Instrument Science Reports
ISRs are technical reports written by members of the NICMOS Group about various aspects of the instrument and data. They usually contain in-depth information about specific topics.
