The MER mission dictionary contains classes and attributes specific to the
MER mission and instruments. This dictionary was created for the migration
of MER data products from PDS3 to PDS4.
Built with LDDTool -plMJ ldd-mer.xml

for a miniTES observation.
Main class to hold parameters related to a
miniTES observation.

This section contains the simpleTypes that provide more constraints
than those at the base data type level. The simpleTypes defined here build on the base data
types. This is another component of the common dictionary and therefore falls within the
common namespace.

The download_priority attribute specifies which
data to downlink/transmit, based on order of importance. The
lower numerical priority (higher-ranked number) data products
are transmitted before higher numerical priority (lower-ranked
number) data products. For example, an image with a downlink
priority of 24 will be transmitted before an image with a
downlink priority of 62. The allowable range is 0 to
99.
Commanded value of the number of icks to acquire
at one azimuth/elevation position.

the butterfly contact switchs.

the RAT SIS for more details.

instrument that was used while acquiring the

signal amplifier.

acquire minus one.

be on at one time.

be on at one time.
The status of the laser
heater.
Provides the status of the Michelson
motor.
The local_true_solar_time_sol element specifies
the number of solar days elapsed since a reference day (e.g. the
day on which a landing vehicle set down) for local true solar
time (LTST). Days are measured in rotations of the planet in
question from midnight to midnight. The reference day is '1', as
landing day is Sol 1.
Commanded value of the start channel number to
acquire. Channel numbers start at zero.
The magnet_id specifies a magnet that is visible
in an image or measured by an instrument.
The maximum RAT revolve motor velocity for a
scan and grind operation.

current.
The maximum allowable travel distance relative
to the RAT z-axis hard stop.
The mission_phase_name identifies a time period
within the mission.
Indicates which of the optical switches was used
by the miniTES optical mirror. There are two switches for
redundancy in case one fails.
Commanded value of the phase correction
algorithm to use on board.
The producer_institution_name specifies the
identity of the facility or institution that produced the
product.
The product_type identifies a group of data
products within a collection that have some property in common,
such as processing level, resolution, or instrument-specific
setting.
The product_version_id specifies the version of
the product. It usually begins with a 'V' and followed by an
identifier for the controlling camera SIS.
Release_id is the identifier of a scheduled
release of MER data from PDS. The first MER data release is
Release 0001. The release_id for a given product is always the
first release in which it appears, and does not change if the
product is revised later.
Specifics the RAT noload current value. Units
are mA, but not given in the label.
Specifics a torque value for the RAT grinding
wheel rotation during a scan or grind operation. Given in units
of mN*meter, but units are not listed in the
label.
Value of the voltage applied to the RAT grinding
wheel rotation motor.
The name of the RAT operation that the rotation
voltage applies.
Commanded value of the number of rows (elevation
steps) to acquire.
Specifics the number of RTIs that are skipped
between telemetry samples in detailed RAT
reports.
Sol_number is the number of the Mars day on
which an observation was acquired. Landing day is Sol
1.
The spacecraft_clock_count_partition provides
the clock partition active for the spacecraft_clock_start_count
and spacecraft_clock_stop_count attributes. This attribute may
be used when the spacecraft_clock values do not include a
partition number.
The spacecraft_clock_start_count is the value of
the spacecraft clock at the beginning of an observation. It
represents the number of ticks. If a fractional value is
present, in some cases it means a true decimal fraction (i.e.
milliseconds) while in other cases it stands for a count of
1/256th of a second (which stems from the fact that the
fractional part was represented by a single byte in the original
telemetry stream.) When comparing SCLK times or converting them
to other time systems, it is important to know which of the two
representations the SCLK string follows. Normally the
documentation accompanying a particular data set defines which
type of SCLK fractional part was used in that data
set.
The spacecraft_clock_stop_count is the value of
the spacecraft clock at the end of an observation. It represents
the number of ticks. If a fractional value is present, in some
cases it means a true decimal fraction (i.e. milliseconds) while
in other cases it stands for a count of 1/256th of a second
(which stems from the fact that the fractional part was
represented by a single byte in the original telemetry stream.)

word.

velocity applies.
