MIDIS image data release

MIDIS data repository This data set contains up to date images of the HUDF in JWST/MIRI filters from the MIRI-EC GTO, and the MIDIS-Red observational programmes. (PIDs: 1283, and 6511). In addition, PSF models for the images are available (based on calibration data from Libralato et al. (2024). The reductions and data quality for the F560W image are described in Pérez-González et al. (2024) and Östlin et al. (2025). The F770W data has been reduced in the same way, and will be described in detailed in Östlin et al. (in prep). If you use the data provided in this repository you should cite Östlin et al., 2025 (https://ui.adsabs.harvard.edu/abs/2025A%26A...696A..57O/abstract).and this Zenodo repository.The MIDIS data will soon be available as a MAST HLSP as well, new Zenodo records with updated versions (adding new data, or runs with updated calibrations/pipeline) will also be created. Images: Images in the F560W and F770W filters are provided. The files are multi-extension fits files output from stage 3 JWST pipeline reductions. The two images are matched in pixel (and sky) coordinates, and the sky coordinates are matched to GAIA sources. Note that the uncertainties per pixel are underestimated in the ERR extensions (see Östlin et al., 2025), and should be used with care. PSF models: In each file there are 9 extensions containing PSF models for different parts of the image. The header contains information on the image coordinates. Versions (current version first in the list): DR1.1 (20250609):- v2.2.8 image versions, based on JWST pipeline version 1.16.1 , pmap: jwst_1303 using RAINBOW v1.6.- v1.1 PSFs, using Libralato et al. (2024) empirical PSF models, inserted and resampled in the MIDIS data (see Boogaard et al. 2024). These PSF models are properly aligned to the images. DR1 (20250528):- v2.2.8 image versions, based on JWST pipeline version 1.16.1 , pmap: jwst_1303 using RAINBOW v1.6.- v1.0 PSFs, using Libralato et al. (2024) empirical PSF models, inserted and resampled in the MIDIS data (see Boogaard et al. 2024). Note that v1.0 are aligned to the detector axis and thus does not properly match the PSFs in the v2.2.8 images. Planned data releases: MIDIS-Red F1000W epoch 1, 2 and combined depth: September 2025.MIDIS-Red F1000W epoch 3 and full depth: Spring 2026
