Drizzle Algorithm
  • Tested for 2 Dragonfly Cluster images (blue filter, no. 1 and 15) from observation 2. Stacking 1 image took approx. 2 hours.
Line: 11 to 11
 Star Scaling
  • Plotted matched stars in a single true data frame and measured data (81 stars)
  • Fitted line of best fit to the stars using equation of a straight line, found parameters using curve fit, use these to calculate scaling problem
