Systematic Mid-infrared Instrument Legacy Extragalactic Survey (SMILES)

The Systematic Mid-infrared Instrument Legacy Extragalactic Survey (SMILES) is a multi-band JWST/MIRI imaging survey of the GOODS-S/HUDF region with NIRSpec spectroscopic follow-up. SMILES covers an area of 34 square arcmin in 8 MIRI bands from 5.6-25.5um (F560W, F770W, F1000W, F1280W, F1500W, F1800W, F2100W, F2550W) plus three NIRSpec Micro-Shutter Array (MSA) masks. Data release 1 (DR1) presents the 8 MIRI mosaics, which have been reduced with custom background subtraction and astrometric corrections (Alberts et al. 2024). These mosaics reach 5 sigma point source sensitivities of 0.2 - 18 uJy (25.6 - 20.9 AB). In addition, a clean catalog with 3,096 sources detected at ≥ 4 sigma in either F560W or F770W is presented. Forced photometry is provided in all other bands, whether the source is detected or not. Cleaning of the catalog, to remove false positives due to noise peaks or cosmic ray showers, was performed using JADES DR2 NIRCam imaging, which is available over the majority of the SMILES area (see Alberts et al. 2024 for details).
