Each record consists of a time tag\nwith 19 scalar data points representing measurements of the electron flux\nin 19 different energy channels, ranging from 10 eV to 20 keV, with an\nenergy resolution of 25%. Each data point is a measure of the electron\nflux (cm-2 sec-1 ster-1 eV-1) averaged over a 360 x 14 degree disk-shaped\nfield of view (FOV). During the Mapping Phase, as the spacecraft orbits the\nplanet the ER field of view sweeps out the entire sky (4-pi ster)\nevery 58.5 minutes, which is much longer than the integration time per\nrecord (2 to 48 sec, depending on energy and telemetry rate) and much l\nonger than most timescales of interest in Mars' plasma environment.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mgs-m-er-3-map1-omnidir-flux-v1.0_9xx3-xbvf", "issued": "2021-05-21", "keyword": ["mars", "mars-global-surveyor"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MGS-M-ER-3-MAP1%2FOMNIDIR-FLUX-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": "MGS MARS/MOONS MAG/ER MAPPING ER OMNIDIRECTIONAL FLUX V1.0"}
