Chhoda Double Star Survey (CHDS): 344 candidate common-proper-motion pairs from Gaia DR3

Catalog of 344 candidate resolved common-proper-motion stellar pairs identified in Gaia DR3 (both components G < 13, separations 2-10 arcsec) not matched as pairs in WDS, WDSS, SIMBAD, El-Badry et al. (2021), Shariat, El-Badry & Bhattacharjee (2026), SUPERWIDE, Tian et al. (2020), Hwang et al. (2022) or Jimenez-Esteban et al. (2019), as queried 2026-09-14. The archive contains: catalog.dat (CDS fixed-width format, 344 records), ReadMe (CDS byte-by-byte description), chds_catalog.csv (full CSV with intermediate selection quantities), and README.txt. For the 28 brightest, widest pairs, an independent second epoch is included from 2MASS (1999.3) and UCAC4 (2000.0), with separations and position angles compared against the Gaia DR3 solution propagated back over the 16-17 year baseline.
