Step 0: copy raw frames to the current directory Step 1: make self sky flat, if --skyflat option is used Step 2: flat field (and bad pixel correction, if --bpm option is used) Step 3: distortion correction, if --dist option is used Step 4: bright object mask Step 5: sky subtraction Step 6: offset measurement Step 7: remove unused images (bad frame etc.) Step 8: shift and combine (2nd iteration for full reduction) Step 9: bright object mask using combined image Step 10: new object mask registration Step 11: make self sky flat frame with new mask Step 12: flat field with new sky flat Step 13: distortion correction Step 14: sky subtraction Step 15: shift and combine
