The Demoulin & Berger Interpretation of LCT
¥Degeneracy: Motions
parallel to B do not directly affect apparent motion of magnetic features.
¥Apparent horizontal motion ULCT is from a combination of horizontal motions and vertical motions acting on non-vertical fields.
¥Apparent horizontal motion ULCT is from a combination of horizontal motions and vertical motions acting on non-vertical fields.
Flows parallel to B donÕt
affect the motion of Magnetic Features. Therefore we
consider
only flows normal to B, and set
v¥B=0.
This constraint, plus the Demoulin & Berger interpretation,
leads to this solution for v^ and vz:
