MOIRCS

The Update for S13B Applicants

2013-02-08

There should be no significant change.

When you apply to the MOS observation, you must explicitly state the required number of MOS masks (both for the Full and the Minimum Number of Nights) in the Sect 11 of the application form. And also, justify why you need the requested number on the technical detail part in Sect 14. Please note that the maximum number of MOS mask available for one contiguous observing period is 15.

Please note that the number of MOS mask will be fixed once it is assigned by TAC's critical reviewing. The request for any backup mask is basically not permitted, unless there are any special reasons.

ANNOUNCEMENT

We are planning to have significant period of instrument closure during early/late 2014 for the MOIRCS Upgrade Project (a.k.a. "nuMOIRCS" Project). Please be aware that the number of MOIRCS nights during 2014 will be limited. We are sorry for the inconvenience.

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 wavelength 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.
