This directory contains all targeted Diviner data of the emission phase function (EPF) for 51 targets acquired up to March 1, 2024 over the course of LRO's 3rd, 4th, and 5th Extended Science Missions. The data are presented in a format similar to the Diviner Reduced Data Record (RDR) products, a complete description of which can be found in the RDR Software Interface Specification (SIS) at the PDS Geosciences Node (https://pds-geosciences.wustl.edu/missions/lro/diviner.htm). For more information on the EPF targeting campaign, please see Bennett et al. (2024): https://www.hou.usra.edu/meetings/lpsc2024/pdf/2311.pdf The products are formatted as both compressed whitespace-delimited text files and compressed CSV (comma-separated) files containing all targeted data since the start of the observation campaign for each target up to 2024-03-01. Some targets have been decommissioned, as they had sufficient data to fully characterize their EPF; see table below for individual start/stop times. All values are expressed as Real 20.9 float values, except for the 'date' and 'utc' fields, which are Character*20. A correction to fix a known pointing offset in Diviner's elevation actuator was applied to update the look vector and projected FOV coordinates (see Powell et al. 2023: https://doi.org/10.1029/2022JE007532), but no additional processing was performed beyond this. The available columns and a short description of each are given below. For further information, please consult the Diviner RDR SIS. index - The ID number associated with each target date - Date of the observation midpoint, e.g. "2021-05-26" utc - Time (UTC) at the observation midpoint, e.g. "16:57:42.628" jdate - Julian date at the midpoint of the observation orbit - Orbit number sundst - The distance from the center of the Moon to the Sun (AU) sunlat - Subsolar latitude sunlon - Subsolar longitude sclk - Spacecraft clock at midpoint of observation (seconds.subseconds). Subseconds range from 0-65535. sclat - Sub-spacecraft latitude sclon - Sub-spacecraft longitude scrad - Distance from center of Moon to spacecraft (km) scalt - Distance from surface of the Moon to spacecraft (km).

Constrained from 110-999 for EPF observations (see SIS). vert_lat - Latitude of orientation vector (see SIS) vert_lon - Longitude of orientation vector (see SIS) c - Channel number (1-9) det - Detector number (1-21) vlookx - x-component of Diviner look unit vector (see SIS) vlooky - y-component of Diviner look unit vector (see SIS) vlookz - z-component of Diviner look unit vector (see SIS) radiance - Calibrated radiance (W m^-2 sr^-1) tb - Calibrated brightness temperature (K) (c3-c9), or radiance relative to normally illuminated Lambert surface at Sun-Moon distance (c1 & c2) clat - Latitude at center of instrument FOV clon - Longitude at center of instrument FOV cemis - Emission angle at center of instrument FOV (0-90). Uses spherical Moon approximation. csunzen - Solar zenith angle at center of instrument FOV (0-180). Uses spherical Moon approximation. csunazi - Solar azimuth angle at center of instrument FOV (0-360). Uses spherical Moon approximation. cloctime - Local time at center of instrument FOV (0-24). Uses spherical Moon approximation. qca - Quality Flag for Calibration (0-255; see SIS) qge - Quality Flag for Geometry (0-255; see SIS) qmi - Quality Flag for Miscellaneous (0-255; see SIS) qual - Noise quality flag (0-2) The target ID numbers, names, coordinates, and dates of first/last recorded observation are given below.
