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.
