This is the readme file for the simulated MIRI data products. 
The simulations and data reductions follow the procedures detailed in Yang et al. (2021, ApJ, 908, 144).


These science and weight images were produced by pipeline_v1.0.ipynb, a jupyter notebook file.
    We note that the pipeline-produced science images from this notebook (v1.0) appear to have 
    striping-like noise in the vertical direction. This issue is due to running the reference 
    pixel correction (refpix) step of Stage 1 on data simulated with MIRISim, as the MIRISim 
    products do not include the effect that refpix is removing. This issue has been fixed in 
    the notebook version 1.1 (pipeline_v1.1.ipynb) that is provided with Part1 and Part2 of 
    this data release.


File explanation:
    The images produced by pipeline_v1.0.ipynb are organized as follows:

        Science images, in units of megajansky per steradian (MJy/sr):
            CEERS{pt_id}/{filter}/final_image.fits 
                {pt_id} is the pointing ID.
                {filter} is the filter name. 
        
        Weight images:
            CEERS{pt_id}/{filter}/final_wht.fits
