2008-11-06: A systematic bias in the photometry is to be introduced when the partial-read mode is used for photometric calibration. The use is not recommended now. See the Information page for more detail. |

We have replaced the channel-1 engineering-grade detector, which has been used during Oct 2007 to June 2008, to the new scientific-grade chip on July 2008. See the the website for more detail. |
Introduction
MOIRCS (Multi-Object InfraRed Camera and Spectrograph) is a wide-field imaging camera and spectrograph. The field of view is 4 x 7 square arcminutes with a spatial resolution of 0.117 arcsec/pixel projected on the sky. To achieve a wide view with high resolution, it uses two HAWAII-2 FPAs covering the focal plane. For imaging mode we have the standard YJHKs filters (MKO system) as well as several narrow-band filters.
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.
