                This bundle contains solar irradiance spectra in 1-nm bins from 0-190 nm. The
                spectra are generated based upon the Flare Irradiance Spectra Model - Mars
                (FISM-M) using the EUV calibrated band irrandiance and interpolated
                Earth-based solar indices and measurements as proxies. The data were provided 
                by the MAVEN EUV team in CDF format.

                    MAVEN Release 18 (2019-08-27): This version is full redelivery of the MAVEN 
                    EUV modelled data bundle, including the inital release of the data covering 
                    2018-11-15 through 2019-05-14. The modelled daily and minute products have 
                    undergone updates in the processing pipeline and in the model coefficients
                    resulting in improved production efficiency and model uncertainty. Some of 
                    the irradiances have changed considerably from previous versions, rendering 
                    the older versions obsolete. The minute products have also been re-tuned to 
                    use other proxies when the EUV Channel B (0-7 nm) irradiances are not 
                    available after the anomaly in that channel. Note that the L3 daily product 
                    model does not use the Channel B irradiances as a proxy, only the minute 
                    product model does.

                    MAVEN Release 16 (2019-02-15): This version is an incremental release of the 
                    MAVEN EUV modelled 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 file contents, and a revised version of the SIS.

                    MAVEN Release 13 (2018-05-15). This release consists of the initial release 
                    of the data covering 2017-11-15 to 2018-02-14, plus the re-release of all 
                    of the previously released data. Total coverage is 2014-10-19 to 2018-02-14. 
                    This version of the data data (rev 02, ver 11 data files), correct an error
                    in the flags. 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 CDF attributes and PDS label Reference_List.

                    MAVEN Release 11. This release consists of the initial release of the daily 
                    data for 2017-05-15 to 2017-08-14, plus the re-release of all all of the 
                    previously released daily 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.

                    in the model that was causing occasional, small steps in the data. This release 
                    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.
