# Output: Detected cmemap with the following characteristics:
# 
#    CME: CME number 
#   Flow: Flow number. Flows are suspicious detections, their color in the detectionmap is dark blue
#     t0: onset time, earliest indication of liftoff
#    dt0: duration of liftoff (hours)
#     pa: principal angle, counterclockwise from North (degrees)
#     da: angular width (degrees), 
#      v: median velocity (km/s)
#     dv: variation (1 sigma) of velocity over the width of the CME
#   minv: lowest velocity detected within the CME
#   maxv: highest velocity detected within the CME
#  halo?: II if da>90, III if da>180, IV if da>270, indicating potential halo/partial halo CME
