make_distortion_maps
(real_xy, detector_xy, step=1)[source]¶ Generate distortion maps based on star positions.
The centres of the returned images correspond to the centre of the detector plane
- Parameters
- real_xylist
[arcsec] Contains 2 arrays: ([x_pos], [y_pos]) where x_pos, y_pos are the coordinates of the real position of the stars
- detector_xylist
[arcsec] Contains 2 arrays: ([x_pos], [y_pos]) where x_pos, y_pos are the coordinates of the detected position of the stars
- stepfloat
[arcsec] the grid spacing of the returned images
- Returns
- dx, dy2D array
Returns two arrays with
