Bundle Description
==================
Overview
--------
This bundle of products is science quality data that is produced directly by
the EUV instrument. It comprises the calibrated data product for the EUV
instrument. In the production process information such as spacecraft attitude
has been considered. There is only one collection product in the EUV
calibrated bundle. The production and validation is the EUV instrument team's
responsibility.

of 2015-05-15 to 2015-08-14.
2.0 2016-02-16 MAVEN Release 4 (2016-02-16): This version includes

updated calibration and improved data production
algorithm.
3.0 2016-05-11 MAVEN Release 5 (2016-05-16): This version includes
a full redelivery of the MAVEN EUV calibrated
data collection generated using a new version of the
EUV data generation software.
4.0 2016-08-15 MAVEN Release 6 (2016-08-15): This version includes
a full redelivery of the MAVEN EUV calibrated data
bundle. In this version the data files include an
additional field indicating the Sun to MAVEN
distance.
5.0 2016-11-15 MAVEN Release 7 (2016-11-15): This version includes
a full redelivery of the MAVEN EUV calibrated data
bundle.
6.0 2017-02-15 MAVEN Release 8 (2017-02-15): These data have been
regenerated using an updated calibration including a
new correction for responsivity variations due to
pointing within the instrument field-of-view, an
improved temperature-gain correction, and an improved
long-term degradation correction.
7.0 2017-05-12 MAVEN Release 9 (2017-05-15): These data have been
regenerated to correct a CDF leap second issue that
appeared in the 2017 data. This includes a full
redelivery of data from 2014-10-18 to 2016-11-14 and
the initial delivery of 2016-11-15 to 2017-02-14.
8.0 2017-08-11 MAVEN Release 10 (2017-08-15): This version of the
bundle includes the following:
- the addition of corrected count rates
- the correction of a 1 second timing error associated
with the leap second at 2016-12-31T23:59:60
- correction of errors in the leap second and
spacecraft clock SPICE kernels listed in the CDF
headers and PDS labels
This release consists of a full re-release of the data
from 2014-10-18 to 2017-02-04 and the initial release of
2017-02-15 to 2017-05-14.
9.0 2017-11-16 MAVEN Release 11. This release consists of the initial
release of 2017-05-15 to 2017-08-14, plus the re-release of
all previously released data. These data have be processed
using new field-of-view, temperature-gain, and degradation
corrections. The new FOV correction is based on a new
technique of using all off-points in addition to the planned
FOV map maneuvers to determine the FOV variability. This has
allowed the expansion of the useable pointing range so that
some data formerly flagged as "bad" for pointing reasons are
now flagged as "good" data. The temperature-gain and
degradation correction updates are improved fits to the
calibration changes tracked throughout the mission.
10.0 2018-02-15 MAVEN Release 12 (2018-02-15): This version includes a full
redelivery of the MAVEN EUV calibrated data bundle, including
the initial release of the data covering 2017-08-15 through

11.0 2018-05-08 MAVEN Release 13 (2018-05-15): This version includes a full
redelivery of the MAVEN EUV calibrated data bundle, including
the initial release of the data covering 2017-11-15 through
2018-02-14. With revision 02 of version 11, an error in the
flags has been corrected. In the previous revision data during
rapid slews of the spacecraft were incorrectly labelled as
'good solar data' resulting in large spikes in the data during
those slews. A rate of slew limit has been incorporated in the
flag criteria, correcting the problem. In addition, a citation
to the paper describing the EUV spectral model has been
included in the attributes. Full coverage is 2014-10-18 to
2018-02-14.

corrections and cross-calibrations with Earth-orbit
measurements by SDO-EVE. Note that, on 23-Nov-2018 Channel B
(0-7 nm) suffered a permanent anomaly rendering it unable to
