Aaron - Image offset parameter investigation: Offset_Parameters.pdf


  • Needed to determine accurate offsets (position and rotation transform) of images.
  • Matched ~30 brightest stars for each image in the Dragonfly cluster (blue filter), comparing to first image in set.
  • Constructed chi-square to compare measured positions in one image to transformed measured positions in offset image.
  • Performed modified least squares fit.
