Astrometry matcher needs to load reference objects relative to max shift/rotation

    XMLWordPrintable

    Details

      Description

      Currently the catalog of reference objects in the matcher is not loaded on a area relative to the max shift/rotation allowed. For larger shifts/rotations/distortions this could lead to portions of the chip being outside of the loaded reference catalog area and thus unconstrained in future wcs fitting.

      Deliverables: Fix to meas_astrom so that it loads an area of the reference catalog relative to the max shift/rotation.

          Description Currently the catalog of reference objects in the matcher is not reloaded after the wcs is corrected. For larger shifts/rotations/distortions this could lead to portions of the chip being outside of the loaded reference catalog area and thus unconstrained in future wcs fitting.

          Deliverables: Fix to meas_astrom that reloads or adds to the reference catalog after the wcs is updated.
