The present data release is based on reductions with  JWST calwebb pipeline v1.6.2 and the calibration context CRDS_CTX = jwst_0970.pmap. In-flight photometric zeropoints were used based on recent measurements by Boyer et al. (2022) and Brammer et al. (https://github.com/gbrammer/grizli/pull/107). In addition, images were background subtracted individually on the "cal" level, and corrected for 1/f noise.   

The release contains:
- 3 short wavelength (SW) filters: F090W, F150W, F200W
- 3 long wavelength (LW) filters: F277W, F336W, F444W

The mosaics are all drizzled to the same pixel scale of 0.03 arcsec/pix, and aligned in both WCS and pixel coordinate:

- PSF-matched mosaics using WebbPSF-generated PSFs and the F444W wavelength as reference.

- A deep stack of the LW images, generally used as a detection image.
