MOIRCS
!! IMPORTANT !!
|
Due to a technical problem in the detector on channel-1, we replaced it to an Engineering-grade chip on 14 Oct, 2007. We will have to operate MOIRCS with this array until a replacement is found. The characteristics of the Engineering-grade chip may not be as good as the previous chip. The data taken by the chip should be handled with enough caution for scientific use. For any updates on the characterization of the detector, please check the dedicated website. We are very sorry for any inconvenience caused by the trouble. |
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.
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) and medium-resolution (R~1300) modes are available. We will also start the open of the high-resolution (R~3000 in Jand H) grisms under the shared-risk basis from S08B.
