Software Interface Specification for HiRISE Reduced Data Record ...

For Planetocentric coordinates and for
Planetographic coordinates in which longitude
increases toward the east, the westernmost
(leftmost) longitude of a spatial area (e.g., a
map, mosaic, bin, feature or region) is the minimum
numerical value of longitude unless it crosses the
Prime Meridian.
TIME_PARAMETERS

MRO:OBSERVATION_START_TIME
UTC start time of observation. This value indicates
when the instrument flight software began the image
acquisition sequence.
START_TIME UTC time of the first image line in the
observation.
SPACECRAFT_CLOCK_START_COUNT
Spacecraft clock count of first image line of the
image observation.
STOP_TIME
UTC time of the last image line in image

observation.
The product_creation_time element defines the UTC
system format time when a product was created.
Formation rule: YYYY-MM-DDThh:mm:ss[.fff]
The mro:ccd_flag element defines the HiRISE CCDs
that were operating at the time of the observation.
The order for the set is RED0, RED1, RED2, RED3,
RED4, RED5, RED6, RED7, RED8, RED9, IR10, IR11,
BG12, BG13.
MRO:BINNING 0, 1, 2, 3, 4, 8, 16
The mro:binning element identifies the binning mode
of each operating CCD. A 0 value indicates the CCD
was not operating. The order for the set is RED0,
RED1, RED2, RED3, RED4, RED5, RED6, RED7, RED8,
RED9, IR10, IR11, BG12, and BG13.
MRO:TDI 0, 8, 32, 64, 128
VIEWING_PARAMETERS
INCIDENCE_ANGLE
EMISSION_ANGLE
PHASE_ANGLE
The mro:tdi element identifies the tdi mode of each
operating CCD. A 0 value indicates the CCD was not
operating. The order for the set is RED0, RED1,
RED2, RED3, RED4, RED5, RED6, RED7, RED8, RED9,
IR10, IR11, BG12, and BG13.

The incidence_angle element provides a measure of
the lighting condition at the intercept center of
the image. Incidence angle is the angle between
the local vertical at the intercept point (surface)
and a vector from the intercept point to the sun.
The incidence_angle varies from 0 degrees when the
intercept point coincides with the sub_solar point
to 90 degrees when the intercept point is at the
terminator (i.e., in the shadowed or dark portion
of the target body). Thus, higher values of
incidence_angle indicate the existence of a greater
number of surface shadows.
The emission_angle element provides the value of
the angle between the surface normal vector at the
image center and a vector from the intercept point
to the spacecraft. The emission_angle varies from 0
degrees when the spacecraft is viewing the
subspacecraft point (nadir viewing) to 90 degrees
when the intercept is tangent to the surface of the
target body. Thus, higher values of emission_angle
indicate more oblique viewing of the target. Values
in the range of 90 to 180 degrees are possible for
ring data.
The phase_angle element provides a measure of the
relationship between the instrument viewing
position and incident illumination (such as solar
light). Phase_angle is measured at the target; it
