APOGLIMPSE: Proper Motion Measurements of the Galactic Plane

The APOGLIMPSE project re-imaged 53 square degrees of the inner Galactic plane, combining new observations with original GLIMPSE data from 2004-2005. It measures proper motions of sources over a decade and includes high-resolution H-band spectroscopy from the APOGEE/APOGEE-2 surveys. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Calculate stellar proper motions based on multi-epoch imaging of the Galactic plane.
• Analyze the kinematics of red giant stars based on combined imaging and spectroscopy.
• Study the structure and dynamics of the inner Milky Way based on a decade-long time baseline.

Strengths

• Covers a specific 53 square degree area of the inner Galactic plane.
• Combines data from two major survey programs (GLIMPSE and APOGEE) for a multi-wavelength analysis.
• Provides a temporal baseline of approximately a decade for proper motion calculations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data volume are unknown, which may limit suitability assessment.
