The InSight mission dictionary contains classes and attributes specific to the InSight mission and its instruments. InSight version 1.8.3.0 last updated 2018-07-10 15:35Z PDS Build 1.10.1.0 LDDTool version 8.1.0 Built with LDDTool -plM ldd-insight.xml The ASCII_Equivalent class contains attributes that identify and locate the ASCII data product equivalent to a given SEIS SEED data product. The Metadata_Location class contains attributes that identify and locate the metadata associated with a given SEIS data product. The Observation_Information class provides information about a science observation. The SEED_Equivalent class contains attributes that identify and locate the SEED data product equivalent to a given SEIS ASCII data product. Attributes specific to the InSight Seismometer data products 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 pds namespace. SEIS data products are archived in their native SEED format and in a PDS-compatible ASCII format. The ascii_equivalent_file_name attribute gives the name of the file that is the ASCII equivalent of a SEED format file. A SEIS data product contains data from a single location and single instrument channel. The channel_name uniquely identifies the location and channel pair using the format NN.AAA, where NN is a two-digit location number and AAA is a three-character channel code (uppercase letters or digits). The complete list of channel names may be found in the Channel Naming document in the SEIS document collection. 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 '0', as Landing day is Sol 0. If before Landing day, then value will be less than or equal to '0' and can be negative. The mars_year element specifies the number of the Mars year relative to the reference date of April 11, 1955 (Mars solar longitude 0), which is defined as the start of Mars year 1. SEIS observations are stored with the seismic data from the instrument in one file (mini-SEED or GeoCSV format) and the metadata for the measurements in another file (dataless SEED or StationXML format). The metadata_file_name attribute gives the name of the file containing the metadata associated with a given data file. The mission_phase_name identifies a time period within the mission. 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. Release_number is the number of a scheduled release of InSight data from PDS. The first Insight data release is Release 1. The release_number for a given product is always the first release in which it appears, and does not change if the product is revised later. Sample_count is the number of samples in a SEIS mini-SEED or GeoCSV product. Sampling_rate represents the number of samples per second (local on-board seconds). Because the instrument (EBox) clock drift is dependent on temperature, sampling_rate various over UTC time. However, this variation is small enough so as to be negligible and can be ignored for scientific analyses. SEIS data products are archived in their native SEED format and in a PDS-compatible ASCII format. The seed_file_name attribute gives the name of the file that is the SEED equivalent of an ASCII data file. SEIS mini-SEED products and their equivalent GeoCSV products contain only seismic data, and therefore have the seis_data_type "waveform". SEIS dataless SEED products and their equivalent StationXML products contain only metadata for the seismic data files, and therefore have the seis_data_type "metadata". Software_name identifies the processing software used to generate a data product. Software_version_id identifies the version of the processing software used to generate a data product. Sol_number is the number of the Mars day on which an observation was acquired. Landing day is Sol 0. 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, it represents the number of 1/65536 ticks. The spacecraft_clock_stop_count is the value of the spacecraft clock at the end of an observation. Start_local_mean_solar_time is the local mean solar time, as defined in the main PDS4 data dictionary, at the beginning of an observation. Start_local_true_solar_time is the local true solar time, as defined in the main PDS4 data dictionary, at the beginning of an observation. Start_sol_number is the number of the Mars day on which a multiple-day observation was begun. Landing day is Sol 0. Start_solar_longitude is the solar longitude, as defined in the main PDS4 data dictionary, at the beginning of an observation. Stop_local_mean_solar_time is the local mean solar time, as defined in the main PDS4 data dictionary, at the end of an observation. Stop_local_true_solar_time is the local true solar time, as defined in the main PDS4 data dictionary, at the end of an observation. Stop_sol_number is the number of the Mars day on which a multiple-day observation was ended. Landing day is Sol 0. Stop_solar_longitude is the solar longitude, as defined in the main PDS4 data dictionary, at the end of an observation.
