The passive\nradiometry measurement is accomplished in a novel fashion by\nmonitoring the noise density at the output of the photodetector and\nsolving for the amount of background light. The passive radiometry\nmeasurements provide images of Mars at 1064-nm wavelength over a 2 nm\nbandwidth with sub-km spatial resolution and with 2% or better\nprecision under full illumination.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mgs-m-mola-3-prdr-l1a-v1.0_k5bz-3wec", "issued": "2021-05-21", "keyword": ["mars", "mars-global-surveyor"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MGS-M-MOLA-3-PRDR-L1A-V1.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "MOLA PRECISION RADIOMETRY DATA\n                                   RECORD"}
