Provides the temperature, in degrees Celcius, of an instrument or
some part of an instrument.
For the APXS data, this is the temperature of the electronics box at
the alpha pre-amplifier at the begining and end of each accumulation
cycle. There will be at most 10 pairs. Mesured in degrees
centigrade.
Degrees = ( x 1.5541) - 273.6
Instrument Compression
Blocks
Provides the number of blocks used to spatially segment a data
product prior to compression.
Instrument Compression
Name
Identifies the type of on-board compression used for data storage
and transmission. Note: The inst_cmprs_mode element provides an
abbreviated identifier for the inst_cmprs_name.
Linear
Accelerometer
X and Y readings for linear accelerometers on the Rover at
STOP_TIME. X indicates pitch, where positive values indicate Rover
front is lower; Y indicates roll, where positive values indicating
right side is lower. Values are the raw counts from the telemetry.
The conversion factor to have this value in units of 'g' is
0.0009765.
MPF Local Time
Local time at the lander site on the surface of Mars, meaured in
local hours, minutes, and seconds, from midnight. Local hours are
defined as one twenty-fourth of a local solar day. Local minutes are
one sixtieth of a local hour, and local seconds are one sixtieth of a
local minute. Format is "hh:mm:ss".
Observation Name
The purpose of an observation or sequence of commands.
Packet Creation
SCLK
SCLK from the primary telemetry packet header of the 1st packet of the
image. Used for requesting image packets from TDS.
Planet Day Number
The Martian day (ie., sidereal day, equal to a rotation of 360
degrees) on which the image was taken. Starts with 1 as the first day
of surface operations, the day the spacecraft landed. Negative values
refer to pre-surface images.
Product Id
Represents a permanent, unique identifier assigned to a data
product by its producer. Note: In the PDS, the value assigned to
product_id must be unique within its data set.
Received Packets
Provides the total number of telemetry packets which constitute a
reconstructed data product.
Rover Heading
Angular measure clockwise from Lander north in BAMS (Binary Angle
Measurement, where 216 BAMS equals one revolution).
Rover Position
X and Y offsets in meters north and east, respectively, of the
Lander reference. (This is a two element array in data object labels,
but two separate values in index tables.)
Sampling Duration
Spectrum accumulation time as returned in the first two bytes of
the spectrum data.
Solar Azimuth
One of two angular measurements indicating the position of the
Sun as measured from the lander. The azimuth is measured positively
in the clockwise direction (as viewed from above) with the meridian
passing through the positive spin axis of the planet (ie., the north
pole) defining the zero reference.
Solar Elevation
One of two angular measurements indicating the position of the
Sun as measured from the lander. The elevation is measured up from
the plan which is perpendicular to the line passing between the lander
and the center of Mars and which intersects the lander.
Spacecraft Clock
Start Count
Provides the value of the spacecraft clock at the beginning of a time
period of interest.
Spacecraft Clock
Stop Count
Provides the value of the spacecraft clock at the end of a time
period of interest. Note: for the Rover Camera MIDRs, this is the
SPACECRAFT_CLOCK_START_COUNT from the latest acquired EDR used as
input to a mosaic.
Start Time
Provides the date and time of the beginning of an event or
observation (whether it be a spacecraft, ground-based, or system
event) in UTC system format. Formation rule:
YYYY-MM-DDThh:mm:ss[.fff]
Stop Time
Provides the date and time of the end of an observation or event
(whether it be a spacecraft, ground-based, or system event) in UTC
system format. Formation rule: YYYY-MM-DDThh:mm:ss[.fff]
