APOGLIMPSE: Galactic Plane Stellar Motions Over a Decade

53 square degrees of the inner Galactic plane were re-imaged to measure stellar proper motions over a decade. The project combines new observations with original GLIMPSE data from 2004-2005. This dataset was published by the National Aeronautics and Space Administration and 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 associated high-resolution H-band spectroscopy.
• Study the structure and dynamics of the inner Galactic plane based on combined imaging and spectroscopic data.

Strengths

• Covers a specific 53 square degree area of the inner Galactic plane.
• Combines observations from two distinct time periods (2004-2005 and later re-imaging).
• Associated with high-resolution H-band spectroscopy for hundreds of thousands of red giants.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and spatial bias inherent to the specific survey area.
