Bundle Contents
===============
Collections
-----------
This bundle includes the following collections:
* w-n - electron density derived from the Langmuir line in the passive and
active spectra
(LID = urn:nasa:pds:maven.lpw.derived:data.w.n)
* lp-nt - electron temperature and density derived from the IV-curves
(lpw.calibrated:data.lp.iv) and, when available, adjusted based on wave
derived electron density (lpw.derived:data.w.n). These products include
the following parameters:
1) Floating potential between spacecraft probe and ambient plasma (
including photoelectrons) (u0)
2) Potential between spacecraft and second product (u1)
3) Spacecraft potential (Vsc)
4) Electron density, total (ne)
5) Electron density population 1 (ne1)
6) Electron density population 2 (ne2)
7) Electron temperature mean (Te)
8) Electron temperature population 1 (Te1)
9) Electron temperature population 2 (Te2)
10) Density proxy based on spacecraft potential (nsc)
(LID = urn:nasa:pds:maven.lpw.derived:data.lp.nt)
* document - documents related to the MAVEN LPW derived data bundle
(LID = urn:nasa:pds:maven.lpw.derived:document)
Data File Naming
----------------
Data files in this bundle are named according to the following convention:
mvn_lpw_❮level❯_❮desc❯_❮yyyy❯❮mm❯❮dd❯_v❮xx❯_r❮yy❯.cdf
where:
❮level❯ = MAVEN processing level of the data
❮desc❯ = A descriptor used to identify the data file type
❮yyyy❯ = 4-digit year of data coverage date
❮mm❯ = 2-digit month of year of data coverage date
❮dd❯ = 2-digit day of month of data coverage date
❮xx❯ = 2-digit software version
❮yy❯ = 2-digit data file version under the specified software version

This archive was produced for the Planetary Data System (PDS) at the Planetary
Plasma Interactions (PPI) node at the University of California, Los Angeles
(UCLA). The data files were generated by Dr. Laila Andersson at the Laboratory
for Atmospheric and Space Physics (LASP) in Boulder, Colorado. The data were
delivered to the PPI node via the MAVEN Science Data Center (SDC) also located
at the LASP in Boulder, Colorado. The PDS metadata were generated at the PPI
node.
