                    products in this release have updated calibrations that have significantly improved 
                    the accuracy of the irradiances. Note that as of 23-November-2018, the EUV Channel B 
                    (0-7 nm) was no longer producing useable science due to a suspected electronics part 
                    failure. The L2 data for Channel B contains a fill value (-1.0E+31) for all times 
                    since the anomaly.

                    MAVEN EUV calibration data bundle, including the initial release of the data 
                    covering 2018-11-15 through 2019-02-14. Full coverage is 2014-10-18 to 
                    2019-02-14. These data have been processed with updated degradation
                    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 produce valid science data after UTC time 
                    17:02:03.748983. Channel B data after this time has been filled with the 
                    value -1.0E+31.

                    MAVEN EUV calibrated data bundle, including the inital release of the data 
                    covering 2018-08-15 through 2018-11-14. This version also includes updates to 
                    the label files contents, and a revised version of the SIS.

                    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.

                <description>
                    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.

                    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.

                    correction, and an improved long-term degradation correction.
