3.0 2018-05-29 MAVEN Release 13 (2018-05-29): This is a full rerelease
of the MAVEN STATIC Calibrated Data Bundle, including the
initial release of 2017-11-15 to 2018-02-14. This release
includes corrections to the "BINS_SC" and "DEAD"
parameters. "BINS_SC" is an integer array used to
identify angle bins that include spacecraft surfaces. The
program generating the "BINS_SC" array had two errors
that partly cancelled placing the spacecraft in roughly
the correct location. New code corrects these errors.
"DEAD" is a dead-time and detector droop correction array.
The program generating the array requires knowledge of
background counts due to penetrating radiation and
radioactive decay in the detectors (which normally
dominates) in order to calculate detector efficiency.
These background rates are generally small and assumed
constant - true for most of the MAVEN mission. That
assumption was invalid for the SEP event in mid-September
2017. Modifications to the code generating the "DEAD"
array were made to calculate the variable background rates
and obtain a more accurate detector efficiency calculation.
These corrections primarily impact the data on Sep 11-14,
2017, although there may be small corrections for weaker
SEP events earlier in the mission.

incremental release of the STATIC calibrated archive,
including the initital release of 2018-02-15 to

3.2 2018-11-14 MAVEN Release 15 (2018-11-15): This version is an
incremental release of the STATIC calibrated archive,
Data set coverage is 2014-09-22 to 2018-08-14.
3.3 2019-02-15 MAVEN Release 16 (2019-02-15): This version is an
incremental release of the STATIC calibrated archive,
Data set coverage is 2014-09-22 to 2018-11-14.
3.4 2019-05-14 MAVEN Release 17 (2019-05-15): This version is an
incremental release of the STATIC calibrated archive.
Data set coverage is 2014-09-22 to 2019-02-14.
3.5 2019-08-08 MAVEN Release 18 (2019-08-15): This version is an
incremental release of the STATIC calibrated archive.
Data set coverage is 2014-09-22 to 2019-05-14.
4.0 2019-11-27 MAVEN Release 19 (2019-11-15): This version is a full
re-release of all of the STATIC calibrated released
to date, and the initial release of data covering
2019-05-15 to 2019-08-14. Full coverage is
2014-10-13 to 2019-08-14. Updates to the data in this
release include the following:
- The ephemeris data (pos_sc_mso) were modified to be
the center time of the measurement rather than the
start time. This amounts to a 2 second time shift
for most products. For averaged data products, like
the D0 product, the time shift is larger depending
on the averaging time.
- The magnetometer (magf) was also modified to use the
center time rather than the start time.
- An error in the calculations of magf was introduced a
couple years ago. Early data CDFs were correct (except
for a small time shift described above), but more
recent data were incorrect. The new CDFs correct these
magf data.
- The quantities magf and pos_sc_mso were included in the
STATIC structures for convenience so that these
information would not have to be acquired elsewhere for
analysis. For most science purposes they are not used.
- A 20% change in absolute geometric factor for the STATIC
sensor based on cross calibrations with LPW.

Data Processing Notes
=====================
Data Timing Uncertainty
-----------------------
Some of the data files in this bundle may extend beyond the time for which the
Spacecraft Clock (SCLK) drift rate was defined based upon the SPICE MAVEN SCLK
kernel used to process them. As a result the SCLK drift rate may have been
predicted, resulting in small errors in the time (typically less than a few
1/100's seconds). Where this may be the case a note has been included in the
individual PDS product labels.
