Definition taken from PDS3 dictionary; may need updating. -- EDR The Mission_Information class provides information about a mission. The Orbital_Mission_Information class provides information about an orbital mission. The Surface_Mission_Information class provides information about a surface mission. 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 mission_phase_identifier attribute provides an identifier for a mission phase. The mission_phase_name identifies a time period within the mission. The product_type_name 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 data from the provider to PDS. The first data release is typically 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. solar_longitude is the solar longitude, as defined in the main PDS4 data dictionary. The spacecraft_clock_partition provides the clock partition active for the spacecraft_clock attribute. The spacecraft_clock_start is the value of the spacecraft clock at the beginning of the observation. The spacecraft_clock_start_count attribute provides the value of the spacecraft clock at the beginning of a time period of interest. The spacecraft_clock_stop is the value of the spacecraft clock at the end of the observation. spacecraft_clock_stop should only be used if there's also a spacecraft_clock_start value. The spacecraft_clock_stop_count attribute provides the value of the spacecraft clock at the end of a time period of interest. start_local_mean_solar_time is the local mean solar time, as defined in the main PDS4 data dictionary. The start_local_mean_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 mean solar time (LMST). 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. start_local_true_solar_time is the local true solar time, as defined in the main PDS4 data dictionary. The start_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 start_orbit_number attribute provides the first in a series of numbers that represent a set of orbital revolutions of one body around another. The start_sol_number is the number of the Mars day on which an observation began. Landing day is Sol 0. stop_local_mean_solar_time is the local mean solar time, as defined in the main PDS4 data dictionary. The stop_local_mean_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 mean solar time (LMST). 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 stop_local_mean_solar_time_sol should only be used if there's also a start_local_mean_solar_time_sol. stop_local_true_solar_time is the local true solar time, as defined in the main PDS4 data dictionary. The stop_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 stop_local_true_solar_time_sol should only be used if there is also a start_local_true_solar_time_sol. The stop_orbit_number attribute provides the last in a series of numbers that represent s set of orbital revolutions of one body around another. The stop_sol_number is the number of the Mars day on which an observation ended. Landing day is Sol 0. The stop_sol_number should only be used if there's also a start_sol_number.
