 Scaled Errors
  • Error on magnitudes now involves scaling parameters

  • where m is the initial magnitude before scaling, c is the intercept in the linear fit (from last meeting) and g is the gradient of the linear fit

  • 85 stars, maximum magnitude = 13.300
  • Lower star count in stacked frames possibly due to the stacking of read-out noise in each frame
