“…Since calibration requirements are still TBC, additional hardware might be added within the instrument volume. An IR calibration source based on the heritage of the JWST MIRI calibration system [8] and injected in the center of the M5 mirror has been considered as the first possible solution. The PLM will interface to the SVM via a set of thermally isolating support struts, or bi-pods, and will be radiatively shielded from the SVM and the solar input loads by a set of 3 V-Grooves (VGs).…”

“…The MRS mode of the MIRI (Rieke et al 2015;Wright et al 2015) on JWST utilizes an integral field spectrograph (IFS) that has four image slices producing dispersed images of the sky on two 1024×1024 infrared detector arrays, which provide R= 1300-3600 integral field spectroscopy over a λ=5-28.3 μm wavelength range (Wells et al 2015;Labiano et al 2016). The spectral window is divided into four channels covered by four integral field units: (1) 4.96-7.77 μm, (2) 7.71-11.90 μm, (3) 11.90-18.35 μm, and (4) 18.35-28.30 μm.…”

This work is downloaded from AbstractExoplanet Proxima b will be an important laboratory for the search for extraterrestrial life for the decades ahead.Here, we discuss the prospects of detecting carbon dioxide at 15 μm using a spectral filtering technique with the Medium Resolution Spectrograph (MRS) mode of the Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST). At superior conjunction, the planet is expected to show a contrast of up to 100 ppm with respect to the star. At a spectral resolving power of R=1790-2640, about 100 spectral CO 2 features are visible within the 13.2-15.8 μm (3B) band, which can be combined to boost the planet atmospheric signal by a factor of 3-4, depending on the atmospheric temperature structure and CO 2 abundance. If atmospheric conditions are favorable (assuming an Earth-like atmosphere), with this new application to the cross-correlation technique, carbon dioxide can be detected within a few days of JWST observations. However, this can only be achieved if both the instrumental spectral response and the stellar spectrum can be determined to a relative precision of 1×10between adjacent spectral channels. Absolute flux calibration is not required, and the method is insensitive to the strong broadband variability of the host star. Precise calibration of the spectral features of the host star may only be attainable by obtaining deep observations of the system during inferior conjunction that serve as a reference. The high-pass filter spectroscopic technique with the MIRI MRS can be tested on warm Jupiters, Neptunes, and superEarths with significantly higher planet/star contrast ratios than the Proxima system.

“…The developed instrument model takes into account the nonstationarity of the instrument response through the spectralvariant PSF. Moreover, the above model does not include nonideal characteristics of the detector [14]. All these effects are assumed to be corrected through the pipeline stages of the data reduction plan [15].…”

Abstract-In this paper we propose an approach of image restoration from multispectral data provided by an imaging system. We specifically address two topics: (i) Development of a multi-wavelength direct model for non-stationary instrument response that includes a spatial convolution and a spectral integration, (ii) Implementation of multispectral image restoration using a regularized least-square, based on a quadratic criterion and minimized by a gradient algorithm. We test our approach on simulated data of the Mid-InfraRed Instrument IMager (MIRIM) of the James Webb Space Telescope (JWST). Our method shows a clear increase of spatial resolution compare to conventional methods.
