These movie clips are based on two epochs of observation in 1997 and 1998 using the HALCA
satellite of the VLBI Space Observatory Programme
(VSOP)
and various ground arrays which included antennas of the Very Long Baseline Array and Very
Large Array of the
National Radio Astronomy Observatory (
Cheung, Ulvestad,
Vestrand, and Stacy 2003). The linear interpolation of images were performed with the
Brandeis movie making AIPS script "BAMM," available to the public. See some other
superluminal magnetic movies
made from the BAMM scripts.
