Coronagraphy Observing Strategies

You are here

R~5000 infrared IFU spectroscopy at AO resolutions using the 0."2 or 0."5 occulting disks for coronagraphic measurements is available. The best performance is achieved in the H and K bands. Coronagraphy can be carried out with or without ALTAIR's field lens, and with or without a NIFS OIWFS guide star. However, for best results, use of the field lens and OIWFS is recommended (OIWFS is currently not available). It is important to note that minimum of support is offered for the coronagraphy mode and the mode is better suited to users with previous experience with coronagraphic data and with coronagraphy observing strategies.
