Phase diagram of projected position vs. velocity for the 5 measured coronal rain blobs (in green). The solid green lines are polynomial fits to the measurements. The solid thin curves are numerically generated paths for blobs of negligible mass starting at random positions between 0.3L and 0.65L and speeds between −25 km s^-1 and 25 km s^-1 for amplitudes ranging from a = 0.01 to 0.5.
