The Update for S14B Applicants

2014-05-07

!!! 2014-05-07 Update: NO Downtime will happen during S14B for nuMOIRCS !!!

If you have any specific questions, please email to the SA.

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 on "nuMOIRCS" Project

We will have significant periods of instrument closure in 2015 Summer for "nuMOIRCS" Project.

Please be aware that the detectors are to be changed to Hawaii2-RG. All electronics related to the detector readout will also be replaced (to ASIC+SAM). The benefit of this is the significant reduction of the overhead for detector readout.

We are also planning to introduce the IFU spectroscopy function to MOIRCS. The date of the downtime is still TBD, though it should happen sometime in 2015. We will update the schedule soon via this 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 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.
