Aaron:

Laura: Threshold set to median background value + sigma/20, where sigma is the standard deviation for each individual image
  • For Aaron's Double Cluster simulation:
    • median background is 917.0
    • sigma is 410.9
    • starfinder counts 445 stars out of 418
  • For the Dragonfly simulation:
    • mean background is 917.0
    • sigma is 635.6
    • starfinder counts 112 stars out of 108
  • For M103 simulation:
    • mean background is 917.0
    • sigma is 152.5
    • starfinder counts 79601 stars out of 92
  • For a visible frame of the Double Cluster, at 30 s exposure, with median pixel value of 1040:
    • Threshold initially set at 1090, then increased by 50
