Offset_Parameters.pdf
Summary:
- 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.
