209 PDS DSV 1 The EPF data products contain all targeted Diviner data of the emission phase function (EPF) for 51 targets acquired up to March 1, 2024, over the course of the Lunar Reconnaissance Orbiter's 3rd, 4th, and 5th Extended Science Missions (Bennett et al., 2024a). EPF observations provide information about the angular infrared emissivity of the lunar surface and can yield constraints on the lunar surface roughness and composition. Accurate models of the lunar EPF will be important for any future instruments with off-nadir temperature measurements that must be normalized to a standard viewing angle. 20159270 Line-Feed Comma 35 0 index 1 ASCII_String The ID number associated with each target. date 2 ASCII_String Date at the midpoint of observation (SCET, UTC). e.g., "2025-06-25". utc 3 ASCII_String Time at the midpoint of observation (SCET, UTC). e.g., "19:35.37.440". jdate 4 ASCII_Real Julian Date at the midpoint of observation (SCET, UTC). e.g., 2454102.123456789. orbit 5 ASCII_Integer Orbit number. 0 to 99999. 99999 0 sundist 6 ASCII_Real AU The distance from the center of the moon to the sun (AU). e.g., 1.00001. sunlat 7 ASCII_Real degrees Subsolar Latitude (deg). -1.7 to 1.7 degrees. 1.7 -1.7 sunlon 8 ASCII_Real degrees Subsolar East Longitude (deg). -180.00000 to 180.00000. 180.00000 -180.00000 sclk 9 ASCII_Real Spacecraft clock at midpoint of observation (seconds.subseconds).
