Current estimates are that the overheads associated with each new science target (for target acquisition, telescope, WFS and instrument re-configuration etc) depend upon the guide configuration chosen for the observation.
Setup times for various observation types are:
This section contains information on the sensitivity and performance of NIFS in its various observing modes. Go directly to:
All links will need updating when GNIRS pages are in place
The optical elements of GNIRS (e.g. cameras, gratings, cross-dispersing prisms and slits) are described in detail on the GNIRS components (broke) pages.
The optical elements of GMOS (e.g. filters, gratings and slits) are described in detail on the main GMOS pages.
The observing condition constraints define the poorest conditions under which a queue-scheduled observation should be executed and indicate the conditions that can be expected by classically-scheduled observers. See the detailed translation between frequency of occurrence (the %-ile bin) and physical property, which is a function of observing wavelength and zenith distance of the source.
This page describes some telescope properties relevant to ITC calculations. See the Gemini telescope pages for more details.
The Gemini coating chamber is capable of depositing either alumini(u)m or silver. Currently the primary, secondary and tertiary (science fold) mirrors on both telescopes are silver coated. This graph shows the reflectivity of Al and Ag.
