Slit Positions in HH 47A
Top: HST images of HH 47A in H-alpha (left) and [S~II] (right) taken
from Heathcote etal (1996). The FOS slit positions of the bow shock (BS) and
Mach disk (MD) are shown superposed upon the H-alpha image.
The directions north and east are shown. The position angle of the slit
was 326.9 degrees for both the MD and BS observations.
Bottom: The H-alpha - [S II] image of HH 47A from Heathcote etal (1996), showing
positions of the shock fronts as strong H-alpha emission.
Arrows denote motion of the gas with respect to
HH 47A, which itself moves away a young star located well off the lower
right portion of the figure.
