| description | The exquisite angular resolution and sensitivity of JWST is opening a new
window for our understanding of the Universe. In nearby galaxies, JWST
observations are revolutionizing our understanding of the first phases of star
formation and the dusty interstellar medium. Nineteen local galaxies spanning a
range of properties and morphologies across the star-forming main sequence have
been observed as part of the PHANGS-JWST Cycle 1 Treasury program at spatial
scales of $\sim$5-50pc. Here, we describe pjpipe, an image processing pipeline
developed for the PHANGS-JWST program that wraps around and extends the
official JWST pipeline. We release this pipeline to the community as it
contains a number of tools generally useful for JWST NIRCam and MIRI
observations. Particularly for extended sources, pjpipe products provide
significant improvements over mosaics from the MAST archive in terms of
removing instrumental noise in NIRCam data, background flux matching, and
calibration of relative and absolute astrometry. We show that slightly
smoothing F2100W MIRI data to 0.9" (degrading the resolution by about 30
percent) reduces the noise by a factor of $\approx$3. We also present the first
public release (DR1.1.0) of the pjpipe processed eight-band 2-21 $\mu$m imaging
for all nineteen galaxies in the PHANGS-JWST Cycle 1 Treasury program. An
additional 55 galaxies will soon follow from a new PHANGS-JWST Cycle 2 Treasury
program. |
