The Commercial Lunar Payload Services (CLPS) mission dictionary contains classes and attributes specific to CLPS deliveries and their instruments. CLPS version 1.1.0.0 PDS Build 1.19.0.0 LDDTool version 14.0.13 Built with LDDTool -plJ PDS4_CLPS_IngestLDD.xml 2023-06-16 JGW Initial version. 2023-06-22 JGW Added CLPS_NIRVSS_Parameters class. The CLPS_Delivery_Information class provides information about a CLPS delivery. The CLPS_Observation_Information class provides information about a science observation. The CLPS_Parameters class is a superclass containing all CLPS mission classes. The NIRVSS_Parameters class provides metadata specific to NIRVSS observations. 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. lunar_lander_name identifies the name of the lunar lander. The mission_phase_name identifies a time period within the mission. nasa_delivery_name identifies the delivery name assigned by NASA. Pixel location of the largest value column of the sub-array. Always given in the native Scale 0. Allowable values are from 0 to 2047. Scale factor representing the number 2^N of columns that are averaged onboard by the AIM, where N is the scale factor. For each scale factor, the number of columns is decreased by 1/(2^N) of the native number of columns (2048): for XScale = 0 the image contains the native number of columns; for XScale = 1 the image contains 1/2 of the native number of columns; etc. Allowable values of XScale are 0, 1, 2, 3, 4. Pixel location of the smallest value column of the sub-array. Always given in the native Scale 0. Allowable values are from 0 to 2047. Pixel location of the largest value row of the sub-array. Always given in the native Scale 0. Allowable values are from 0 to 2047. Scale factor representing the number 2^N of rows that are skipped onboard by the AIM, where N is the scale factor. For each scale factor, the number of rows is decreased by 1/(2^N) of the native number of rows (2048) for YScale = 0 the image contains the native number of rows; for YScale = 1 the image contains 1/2 of the native number of rows; etc. Allowable values of YScale are 0, 1, 2, 3, 4. Pixel location of the smallest value row of the sub-array. Always given in the native Scale 0. Allowable values are from 0 to 2047. Time, in milliseconds, that the chosen LED is in the illuminated or on state. Typically LED illumination duration time equals the image exposure duration. However, when the image exposure duration exceeds the LED's maximum allowable exposure, the LED will turn off at the maximum allowable exposure, while the detector continues acquiring the image. The producer_institution_name specifies the identity of the facility or institution that produced the product. The product_type element identifies a group of data products within a collection that have some property in common, such as processing level, resolution, or instrument-specific setting. The project_scientist element identifies the name of the delivery's Project Scientist. release_number is the identifier of a scheduled release of data from PDS. The first data release has release_number "0001". 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. The spacecraft_clock_partition provides the clock partition active for the spacecraft_clock_start and spacecraft_clock_stop attributes. This attribute may be used when the spacecraft_clock values do not include a partition number. The spacecraft_clock_start attribute provides the value of the spacecraft clock at the beginning of a time period of interest. The spacecraft_clock_stop_count attribute provides the value of the spacecraft clock at the end of a time period of interest. The vendor element identifies the company responsible for delivering the payload to the lunar surface. vendor_mission_name identifies the name given to the mission by the CLPS vendor.
