Photometric and Astrometric Information for Sources around HD 163296 Revealed by JWST/NIRCam Coronagraphy.

Abstract (from CDS):

Background stars observed through a circumstellar disk provide valuable benchmarks for investigating the disk's extinction properties. The HD 163296 system is an excellent case study due to its large disk, the clearly visible extinction effects in JWST/NIRCam data, and the presence of numerous background sources within or around its disk. We present the measured contrasts and astrometry of sources surrounding HD 163296 from Cycle 1 JWST/NIRCam coronagraphic observations, which will serve as a useful reference for future studies of the disk's extinction characteristics.
