The Update for S19A Applicants
MOIRCS is in Regular Operation
MOIRCS will be operated under the "regular" status during S19A Semester.
However, we note that currently the Subaru telescope cannot offer the Arc lamp function due to the trouble on its circuit. Thus we cannot use it for the wavelength calibration of spectroscopy observation. The fixing plan is still TBD and it may take long time. Note that we can still do the wavelength calibration using the OH night lines. Please contact the SA if you have any concern.
Please carefully read the following MOIRCS webpages before you design your observing strategy. If you have any question, please contact the primary support astronmer (see the bottom of the page).
For MOS Applicants
When you apply MOS observation, you must explicitly specify the required number of MOS masks (for both the FULL and the MINIMUM number of nights) in the Section 16 (Instrument Requirement) of the application form, with a clear justification for these numbers in Section 14 (Technical Justification).
The UH proposals must also follow the same rule.
The number of MOS mask will be fixed once it is assigned by TAC's critical reviewing. See the end of MOS observation page for the backup mask policy.
Please note that the maximum number of MOS mask available for one contiguous observing period is 15.
You will need a FITS image of your MOS target field for mask design. If you don't have any images for the design, we recommend to use the Pan-STARRs images or the HSC SSP images after converting it to the MOIRCS pixel scale.
If you have special reason to ask taking the preimaging data by MOIRCS ("preimage observation"), please explicitly request it (with justification) in the proposal (Technical Justification). And also, please contact the support astronomer about the execution of the preimage as soon as possible after your schedule is fixed.
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 2048×2048 infrared detector arrays with the spatial resolution of 0.116 arcsec/pixel. The detector has been updated to the Hawaii2 RG in late 2015.
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 aluminum slit masks, MOIRCS can acquire 40 ~ 60 object spectra simultaneously across 0.9~2.5 micron wavelength range. The low-resolution (R~500) and high-resolution (R~3000) grisms are available (the R1300 medium-resolution grism is also available but have some issues). See the Spectroscopy Page for more details. All MOS observers/applicants should carefully read the MOS observation pages.
