orientation and sense of rotation of the spacecraft and the optical
inversion properties of the camera system involved, MOC images can
either be normal or flipped left-for-right (independent of whether the
image is north up or south up.) This flag will be 'F' if the image
should be flipped left-to-right, and 'N' if it is already in normal
form."

DESCRIPTION = "The angle in degrees clockwise from the reference axis
of the image (a line from the center to the right edge of the image)

"The image skew angle is the absolute value, in degrees, of the angle
between the left edge (a line between the lower left and upper left
corners) and the bottom edge (a line between the lower left and lower
right corners) of the image, where the edges are projected on the
target body. For images whose footprints are exactly rectangular,
this angle will be 90 degrees. Departures from 90 degrees indicate a
non-rectangular image footprint, caused by slews of the spacecraft
during imaging outside the orbit plane or off-nadir pointing, or
both."

NAME = RATIONALE_DESC
COLUMN_NUMBER = 51
DESCRIPTION = "A text description of the scientific purpose for the
acquisition of this image. For routine mapping operations, this will

if the image missed its target significantly, the atmosphere was
cloudy, gain parameters were set inappropriately, etc.)"
