Mars Atmosphere and Volatile EvolutioN (MAVEN) Extreme Ultraviolet Moniter (EUV) Calibrated PDS Archive Bundle LID = urn:nasa:pds:maven.euv.calibrated 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.

These are all EUV version 05, revision 02 products produced with an 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 2017-11-14.

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.
