The high image quality of NICMOS can be characterized by the Strehl ratio of the PSF, namely the ratio of the observed PSF to the TinyTim PSF peak fluxes. This ratio is very high for NICMOS, ranging from 0.8 to 0.9 at all wavelengths and in all cameras at their optimal focus. Important information on Image Quality can be found in the Image Quailty section of Chapter 4 of the NICMOS Instrument Handbook. For more specific details on NICMOS image quality, follow the links to the documents listed below.
