This release consists of a full redelivery of SWEA data going back to 2014-11-15, and including the initial release of 2023-11-15 to 2024-02-14. Here’s a list of improvements: (1) Quality flag that identifies the sporadic low-energy anomaly. Allows data filtering. Data will no longer masked. They will be provided as is, along with a quality flag. (2) Decrease deadtime from 2.8 to 1.0 microseconds, based on in-flight calibrations. This fixes an over-correction of the data at high fluxes that is present in previous versions. (3) Updated sensitivity to account for SWIA recalibration. (4) Secondary electron contamination is estimated for all three data products. This allows much better estimates of flux, density and kinetic temperature in the magnetosheath and for auroral electrons. (5) Better data sorting at day boundaries. SPEC data are bundled into groups of 16 spectra and time tagged with the first spectrum in the group. At a day boundary, some of the spectra in a bundle belong with the current day and the rest belong with the next day. The new version now properly sorts SPEC data at day boundaries. 2014-10-10T00:00:01.072Z 2025-12-05T23:59:57.537Z Science Calibrated Magnetosphere Particles Electrons Solar Energetic Mars Atmosphere and Volatile EvolutioN Mission Mission urn:nasa:pds:context:investigation:mission.maven collection_to_investigation MAVEN Host urn:nasa:pds:context:instrument_host:spacecraft.maven is_instrument_host Solar Wind Electron Analyzer Instrument urn:nasa:pds:context:instrument:swea.maven is_instrument Mars Planet urn:nasa:pds:context:target:planet.mars collection_to_target EM-5 Transition Prime Mission EM-1 EM-2 EM-3 EM-4 EM-6 urn:nasa:pds:context:resource:resource.maven.swea.calibrated_colxn_data.svy_pad_online has_resource urn:nasa:pds:context:resource:resource.maven.swea.calibrated_online has_resource Data MAVEN SWEA electron pitch angle distributions in units of differential energy flux (eV/cm**2 sec ster eV) at the MAVEN survey telemetry rate collection_data_l2_svypad_v4.9.csv 2026-06-05T13:18:48 327850 ab6a98697b56ab401e36583cfff3c6f4 0 PDS DSV 1 3950 Carriage-Return Line-Feed Comma 2 0 259 Member Status 1 ASCII_String 1 LIDVID_LID 2 ASCII_LIDVID_LID 255 inventory_has_member_product
