for line 1 of the image plus or minus 0.1
seconds.

Solar Azimuth. The angle between two
half-planes, both bounded by the target rotation axis boresight
intersection, one containing Sun, the other parallel to the
anti-normal at the boresight intersection. A value of 180.0
represents coincident half-planes; a value of 0.0 represents
parallel but opposing half-planes. If Boresight Flag NE 1, the
value shall be -9999. Allowed range is 0.0 to
360.0
Local-mean-normal-based Solar Time (LST). The
angle between two half-planes, both bounded by the target
rotation axis boresight intersection, one containing the Sun,
the other parallel to the mean anti-normal calculated from up to
100 vectors in the FOV. A value of 180.0 represents coincident
half-planes; a value of 0.0 represents parallel but opposing
half-planes. If fov_fill_flag is zero, the value shall be -9999.
Allowed range is 0.0 to 360.0
Local-normal-based Solar Time (LST). The hour
angle between two half-planes, both bounded by the target
rotation axis boresight intersection, one containing the Sun,
the other parallel to the anti-normal at the boresight
intersection. A value of 12.0 represents coincident half-planes;
a value of 0.0 represents parallel but opposing half-planes. If
Boresight Flag NE 1, the value shall be -9999. Allowed range is
0.0 to 24.0
Spacecraft Azimuth. The angle between two
half-planes, both bounded by the target rotation axis boresight
intersection, one containing the
boresight-intersection-tospacecraft vector, the other parallel
to the anti-normal at the boresight intersection. A value of
180.0 represents coincident half-planes; a value of 0.0
represents parallel but opposing half-planes. If Boresight Flag
NE 1, the value shall be -9999. Allowed range is 0.0 to
360.0

sub-second time. This number is the fractional numerator out of
65535. The spacecraft clock time tag is the start of exposure

CCD transfer clock pattern. There are 8 bit
periods per the clock cycle. TCK_PATTERN determines the high to
low ratio.
The pass/fail state of the image check sum as
transmitted from the instrument.
Compression mode. 0 means no compression; 0xff
means lossless compression; 1-99 means JPEG compression quality
N, grayscale; 101-199 means JPEG compression quality N, 4:2:2
color subsampling. JPEG compression can only be applied to 8-bit
data. Note that if a color camera image is compressed as
grayscale, compression efficiency may be degraded. Keyword may
be blank if the transmit-image-raw command was used to acquire
image.
Turns 2x2 summing on or off. Legal values are 1
(no summing) and 2 (2x2 summing.) Summing can only be applied to
8-bit data. Images with both compression and summing selected
will be compressed but not summed. Keyword may be blank if the
transmit-image-raw command was used to acquire
image.
