Astrometry Page


This page contains information, utilities, and procedures related to NIRC2 Astrometry.
This section provides recent results from the GC group:

Sylvana Yelda has done a great job documenting NIRC2 distortion and the results are presented in this paper: S. Yelda et al. 2010, ApJ, 725, 331
Many thanks to the UCLA Galactic Center Group for making this information available.
This section provides IDL source code (graciously provided by Keck Observer Brian Cameron) for removing geometric distortion from NIRC2 images. The use and methodology of the code is well described in the comment headers.
This section contains a link to a related report (also provided by Brian).
This section contains recommended astrometric calibration fields.
