StarID.query_catalog

giant.stellar_opnav.star_identification:

StarID.query_catalog(image)

This method queries stars from the catalog within the field of view.

The stars are queried such that any stars within 1.3*the CameraModel.field_of_view value radial distance of the camera frame z axis converted to right ascension and declination are returned between min_magnitude and max_magnitude. The queried stars are updated to the image.observation_date value using proper motion. They are stored in the queried_catalog_star_records attribute. The stars are stored as a pandas DataFrame. For more information about this format see the Catalog class documentation.

In general, this method does not need to be directly called by the user as it is automatically called in the project_stars() method.

Parameters:

image (OpNavImage) – The image to querry the catalog for (specifying the time and the a priori pointing)
