pyklip.kpp.detection.detection.point_source_detection(image, center, threshold, pix2as=None, mask_radius=4, maskout_edge=None, maskout_inner_edge=None, IWA=None, OWA=None)[source]

Find the brightest blobs in the image/cube.

Parameters:
  • image – Image from which to get the SNR map
  • center – center of the image (y_cen, x_cen)
  • threshold – Threshold under which blob should be ignore.
  • pix2as – Platescale (arcsec per pixel).
  • mask_radius – Radius of the mask used for masking point sources or the surroundings of the current pixel out of the data. Default value is 4 pixels.
  • maskout_edge – mask a maskout_edge (int) pixels around the outer edge of the FOV containing NaNs.
  • maskout_inner_edge – mask a maskout_inner_edge (int) pixels border around the center nan disk.
  • IWA – inner working angle in pixels.
  • OWA – outer working angle in pixels.
Returns:
