MOIRCS
The update for S11A ApplicantsThe situation of MOIRCS for S11A open-use is basically the same as before. For the imaging mode, a new filter (BrGamma:) may become available from 2011A semester under the shared-risk operation. The basic characteristics of the filter is hopefully to be checked in late 2010 after the installation in August. Contact the SA for more detail. Note that NO narrow-band filters are available for the Service Observation. When you propose the MOS observation, the number of the MOS mask must explicitly be given in the Sect.11 of the application form. The number of MOS mask should be carefully determined, because it is not allowed to change it later once it is approved by the TAC after the critical reviewing. The request for any backup mask is basically not permitted, though you may request it later to the observatory if there is any special reasons. Note that the use of the VPH grisms is under the shared-risk policy. Proposers planning to use the VPH should well understand its complex characteristics through the VPH website. |
Introduction
MOIRCS (Multi-Object InfraRed Camera and Spectrograph) provides wide-field imaging and long-slit / multi-object (MOS) spectroscopic capabilities in the 0.9 ~ 2.5 µm spectral range under the natural seeing condition. The 4'×7' field of view is covered by two Hawaii-2 2048×2048 arrays with the spatial resolution of 0.117 arcsec/pixel.
For the imaging mode, the standard MKO YJHKs filters as well as some narrow-band filters are available. See the Imaging Mode Page for more details.
The MOS performance of MOIRCS spectroscopy mode is the most notable feature of the instrument. Using the cooled aluminium slit masks, MOIRCS can acquire about 40 object spectra simultaneously across 0.9~2.5 micron wavelengths range. Currently low-resolution (R~500), medium-resolution (R~1300), and high-resolution (R~3000) modes are available. See the Spectroscopy Page for more details. All MOS observers/applicants should carefully read the MOS observation pages.
