    • GPIPS DR4 Unique Star Catalog

    Metadata Updated: January 16, 2026

    The Galactic Plane Infrared Polarization Survey (GPIPS) covers 76 sq. deg. of the first Galactic quadrant midplane, 18<l<56 deg and -1<b<+1 deg, in H-band (1.6 micron) linear polarimetry to reveal the plane-of-the-sky orientation of the magnetic field in diffuse and denser atomic and molecular clouds. The Survey consists of 3234 overlapping 10x10 arcmin fields observed using the Mimir instrument on the 1.8 m Perkins telescope.The unique star data file (Clemens et al. 2020) collects all GPIPS photometry and polarimetry and all matching stellar data appropriate to each GPIPS star. The unique star file contains entries for 13,861,329 GPIPS stars.
