status of the scan motor mode. 1 --> high power; 0 --> low
power.

viewed point to the sun and one from the viewed point normal to
its tangent plane. The range of solar zenith angle is 0 to

sensor reference voltage.

sensor reference voltage.
TIME_ERROR The current scan line does not have the expected time
and the fact cannot be explained by a detected data gap or by a
scheduled correction to the spacecraft clock. Generally this
means that the difference between the time of the current scan
and the most recent previous scan having a good time is not
evenly divisible by the scan period. Set by the PDP based upon
major/minor frame accounting and the availability of time data
from the spacecraft. <<1b: bytes 29-32, bit 30>>
TIME_OF_DAY_OF_SCAN the time of day in milliseconds of the start
of the scan. Set by the PDP based upon the date and time
information provided in the data stream. Scan times are obtained
from the time of the TIP major frame with an increment added
for each scan period. The scan time refers to the time midway
through the first field of view of the scan. If the time
of the TIP major is not known and in the case of embedded AIP or
TIP, the time will be inferred from the AVHRR frame (GAC or
HRPT).
TIME_PROBLEM_INDICATOR provides an array of boolean codes
indicating the occurrence (or not) of the following conditions:
+
(1) Time received from the s/c was
obviously bad. The time on this scan
has been inferred from those on nearby
scan lines.
(2) Bad time received from s/c and can't
infer one reliably.
(3) Pattern of scan times changed. May be
related to clock update.
(4) Spare.

parameter AYAW. It represents the Euler error angle. See the
Programming and Control Handbook (Reduction of CPU Telemetry)
for instructions for the conversion of this integer value to an
angular measure.
