MAVEN H- Data (2014-2023)
<p>These data were primarily obtained from the Neutral Gas and Ion Mass Spectrometer (NGIMS), Solar Wind Ion Analyzer (SWIA), and Solar Wind Electron Analyzer (SWEA) onboard the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. These data sets were derived from these three instruments' data products and utilized in the article <strong>Characterizing Precipitation Behaviors of H<sup>-</sup> in the Martian Atmosphere</strong>, which is being submitted to JGR: Space Physics. </p> <p>Additional data sets include the list of orbits examined, relevant cross sections mentioned throughout the manuscript, and solar wind conditions derived from MAVEN data & an artificial neural network. </p>

Qualisign: Software Metrics and GoF Design Patterns of the Maven Central Repository
<p>This dataset contains software metric and design pattern data for around 100,000 projects from the Maven Central repository.

MAVEN Ephemeris, Heliocentric Trajectories, Heliographic, Heliographic Inertial, and Solar Ecliptic Coordinates, HelioWeb, Daily Data
Heliocentric trajectories for MAVEN in Heliographic, HG, Heliographic Inertial, HGI, and Solar Ecliptic, SE, Coordinates The original trajectory data are taken from http://ssd.jpl.nasa.gov/horizons.cgi where users can find many more objects. In the case of orbit data for planets, the orbit data can be used as a proxy for spacecraft ephemeris that are in orbit about the planets. On a heliospheric scale, differences between the planet orbital tarjectory and that of the spacecraft are very small. For instance, the heliocentric longitudes differ by only 0.25° for a spacecraft stationed near the L1 Lagrange point at approximately 100 Earth radii upstream of the Earth. The production of the HG, HGI, and SE trajectory data requires a values for the "Equinox Epoch", which is defined as the epoch time when the direction from the Earth to the sun at the time of the vernal equinox when the sun seems to cross equatorial plane of the Earth from below. This direction is called the First Point of Aries, FPA and it is not a fixed direction but drifts by about 1.4° per century or 50.26" per year. In addition, there are tiny irregularities in FPA drift that are on the order of 1" per year or less. The Equinox Epoch can be determined by using a variety of methods for calculating the instantaneous FPA longitudinal direction and whether the tiny irregularities have been smoothed or averaged out. Four methods for determining the Equinox Epoch are in common usage: +---------------------------------------------------------------------+ Method Name FPA Longitude Definition --------------------------------------------------------------------- B1950.0 the actual FPA at 22:09 UT on December 31, 1949 J2000.0 the smoothed FPA at 12:00 UT on January 1, 2000 True of Date the actual FPA at 00:00 UT on the date of interest Mean of Date the smoothed FPA at 00:00 UT on the date of interest +---------------------------------------------------------------------+ The heliocentric trajectory data included in this data product have been calculated by using the Equinox Epoch: defined via the "Mean of Date" method. More precise coordinates, and some planet-centered coordinates, are found in the "traj" subdirectories of spacecraft specific directories at https://spdf.gsfc.nasa.gov/pub/data/ and http://ssd.jpl.nasa.gov/horizons.cgi.

Sun-State, SS, Coordinate System wherein the Primary Reference Vector, the X-axis, points from the Object, in this case Mars, to the Sun and the Secondary Reference Vector, the Y-axis, is in the Mars Orbit Plane, which is approximately opposite to Orbital Motion Direction, such that the Z-axis is Northward. The Observations Spacecraft Payload, PL, Coordinates are suitable for use in association with Measurements obtained by other Instruments on the Spacecraft. The Spacecraft Payload Coordinate System and the MAG Sensor Coordinate Systems are illustrated in Figure 21 of Connerney et al., 2015.
