This dictionary covers nuclear spectroscopy observations.
The records to which this state
applies.
Contains a reference to a document that
describes the energy calibration for the
product.
Specifies a single detector which was active at
the time of observation.
Specifies which detectors were active on an
instrument at the time of observation.
Specifies methods and data used to determine the
pulse height in energy units (e.g. MeV) for each channel of a
pulse height spectrum.
Defines the records to which this state applies
by identifying the first record (inclusive), and the number of
contiguous records, including the first.
Defines the first and last records for which
this state applies. The record numbers are one-based and
inclusive.
This class specifies instrument settings.
Instrument settings may be driven via a state table, which may
be associated with specific observations within the data
product, either by directly indicating those records, or
indicating the observation times at which certain states
apply.
This class specifies properties pertaining to a
nuclear spectroscopy observation.
Describes the times that the activity affecting
nuclear spectroscopy observations was in effect, along with the
sources of the activity, if applicable.
Describes activity that may affect nuclear
spectroscopy observations.
The pulse height in energy units (e.g. MeV) is
determined for a given channel number using the polynomial: H(x)
= a0 + a1 x + a2 x^2 + ..., where H is pulse height with energy
units and x is channel number.
Describes a single term in the polynomial
function.
Specifies an additional look-up table that
provides additional information about specific observations
within the product.
Associates individual observations in the data
product with a record in the state table, providing additonal
information on those observations.
The time during which this state was applicable.
The state table entry is applicable to records in the referenced
data table if the time of the data record, as given by
state_time_field_name, is between the start time and stop time
given in State_Time.
Ephemeris time, as defined by the referenced
field, for the first and last science data records for a
temporally contiguous block of records with the same state or
affected by the same conditions. These records need not be
contiguous within the file, but there must be no records with a
different state between the start and stop
time.
Spacecraft clock time in ticks since spacecraft
clock start for the first and last science data records for a
temporally contiguous block of records with the same state or
affected by the same conditions. These records need not be
contiguous within the file, but there must be no records with a
different state between the start and stop
time.
Universal Coordinated Time for the first and
last science data records for a temporally contiguous block of
records with the same state or affected by the same conditions.
These records need not be contiguous within the file, but there
must be no records with a different state between the start and
stop time.
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 coefficient of a single term of the
polynomial relating channel number to pulse
height.
Any notes about the state at the time of
observation.
A flag indicating whether the condition was in
effect at the given time.
A string identifying the source of the condition
at the given time.
Remarks about the containing
object.
A description for the
detector.
The earliest ephemeris time, as defined by the
referenced field, for which this state or condition is
applicable.
The latest ephemeris time, as defined by the
referenced field, for which this state or condition is
applicable.
The first record for which the state applies,
inclusive.
The last record for which this state applies,
inclusive.
The name of the detector.
The order of a single term of the polynomial
relating channel number to pulse height.
The number of consecutive records, including the
first, for which this state applies.
The earliest spacecraft clock time, in ticks
since spacecraft clock start, for which this state or condition
is applicable.
The latest spacecraft clock time, in ticks since
spacecraft clock start, for which this state or condition is
applicable.
The state_index points to a row of a look up
table containing the instrument settings.
The name of the field in the referenced data
table that contains the time.
The earliest Universal Coordinated Time for
which this state or condition is applicable.
The earliest Universal Coordinated Time for
which this state or condition is applicable.
