JWST/MIRI Data Reduction Pipeline
Abstract
The James Webb Space Telescope (JWST) will launch in 2018 and will carry four science instruments: NIRISS, NIRSpec, NIRCam and MIRI. MIRI (the Mid-Infrared Instrument) will observe the sky at 5 to 28.5 microns and provides four observing modes: imaging, low-resolution spectroscopy (LRS), medium-resolution spectroscopy (MRS) via an integral field unit, and coronagraphy.The MIRI data reduction pipeline is based on extensive testing of the instrument and will provide not only basic calibrated data, but also higher level science products. The pipeline is split into three stages: first, the raw data is processed into an uncalibrated slope image; second, each slope image is calibrated; and third, slope images from multiple exposures are combined and processed to produce the final data product. The final data products include: calibrated mosaics and catalogs of point sources for imaging observations; extracted spectra for LRS observations; PSF subtracted images for coronagraph observations; and spectral cubes for MRS observations. The overall goal of the MIRI pipeline is to provide well-calibrated, high level data products that maximize the scientific return from the instrument.
