Data in RTN <_ResourceName>Source: Master/CDFglobalAttributes/Logical_source_description wi_h1_swe_RTN <_AlternateName>Source: Master/CDFglobalAttributes/Logical_source Notes: - Data reported within this file do not exceed the limits of various paremeters listed in the following section. There may be more valid data in the original dataset that requires additional work to interpret but was discarded due to the limits. In particular we have tried to exclude non-solar wind data and questionable alpha data from these files. - We provide the one sigma uncertainty for each parameter produced by the non-linear curve fitting analysis either directly from the fitting or by propagating uncertainties for bulk speeds, flow angles or any other derived parameter. - For the non-linear anisotropic proton analysis, a scalar thermal speed is produced by determining parallel and perpendicular tmperatures, taking the trace, Tscalar = (2Tperp + Tpara)/3 and converting the result back to a thermal speed. The uncertainties are also propagated through ; Limits: ; Minimum mach number: 1.5000000 ; Maximum chisq/dof: 100000.00 ; Minimum distance ; to bow shock: 5.0000000 [Re] ; Maximum uncertainty in any ; parameter from non-linear ; analysis: 70.0000[%] <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ <_DOI>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/DOI.json <_AccessInformation>Source: https://github.com/rweigel/cdawmeta-spase/blob/main/AccessInformation.json 1994-11-17T19:50:45Z 2025-06-22T23:58:43Z <_TemporalDescription>Generated from all.xml/@timerange_start and all.xml/@timerange_stop PT1M14.642S <_Cadence>Counts based on variable 'Epoch' in https://cdaweb.gsfc.nasa.gov/sp_phys/data/wind/swe/swe_h1_rtn/1994/wi_h1_swe_rtn_19941117_v01.cdf.
