MAVEN SWIA Calibrated Onboard Survey Spectra Data Collection
Short Name:
SWIA-ONB-SVYSPEC
Date:

Publisher:
Planetary Data System
Description:
SWIA onboard spectra files with time-ordered angle-averaged ion
energy spectra in units of differential energy flux, as computed
onboard from Coarse ion distributions, as well as a header with
ancillary information needed to interpret the spectra.
The database contains some outputs of the MCD for all the scenarios
available, at different positions of latitude and longitude. These MCD
outputs are provided as Votables containing profiles of temperatures,
pressures, density and abundances of O2 and O3 for altitudes between 0
and 249.5 km from the surface.
MCD is a database of atmospheric statistics compiled from Global Climate Model (GCM) numerical simulation of Martian atmosphere (<a href=http://www-mars.lmd.jussieu.fr>http://www-mars.lmd.jussieu.fr</a>). The GCM computes in 3D the atmospheric circulation and climate taking into account radiative transfer through the gaseous atmospheres and the dust and ice aerosols, includes a representation of the CO2 ice condensation and sublimation on the ground and in the atmosphere, simulates the water cycle (with modelling of cloud microphysics), the dust multisize particle transport, the atmospheric composition controlled by the photochemistry and the local non-condensible gas enrichment and depletion induced by CO2 condensation and sublimation, and has been extended into the thermosphere and to model ionospheric processes (due to chemistry). The database extends up to exobase (the top of the thermosphere, roughly at 300km in altitude); in addition to statistics on temperature, wind, pressure, radiative fluxes, it provides data such as atmospheric composition (including dust water vapor and ice content) and make use of 'dust and Extreme Ultra Violet (EUV) scenarios' to represent the variation of dust in the atmosphere and solar EUV conditions.

at the same cadence as the EPS LoRes Spectral rate measurements. Each
file thus has a one-to-one relationship with a corresponding LoRes
spectral file.
Contains alternating current (AC) level values at the commanded
sample rate. To conserve telemetry the vector sampling will usually be
less than the maximum rate, 20 sample/s. To provide a record of the
amplitude of fluctuations for frequencies higher than 1 Hz, an AC
amplitude is calculated from the internally sampled 20/s data for the
sensor axis commanded as the AC_AXIS. Thus, in addition to the vector
samples data, a 1 Hz to 10 Hz bandpass average amplitude is evaluated
for the commanded sensor axis, selected by command, and recorded as a
log AC value with a 4-bit mantissa of the four most significant
non-zero bits and a 4-bit power of two exponent of the 4th (least
significant) bit of the mantissa. This is called the logAC value. It
is created once per second and saved for telemetry at that rate or at
the commanded science rate, whichever is less frequent.
A cumulative file for the entire mission. The purpose of the file is
to keep a time log of bursts recorded by the instrument, as well as
the number of burst packets recorded for each Burst EDR.

TITAN is a computer program for calculating the interactions of a dilute plane-parallel medium with electromagnetic radiation. It includes all atomic processes: absorption, recombination, diffusion, excitation, deexcitation of atoms and ions, heating and cooling of the gas, and it solves the radiation transfer, in order to obtain the spectra reemitted by the medium. It handles plan parallel slabs in non LTE steady state, for various physical conditions and various illuminations, valid in many astrophysical situations. It is specifically designed for warm-hot (8000 to 10**8 K) and thick media (till an electron scattering optical depth of several tens) emitting and absorbing in the X-ray range (density from 10**5 to 10**14 cm-3). It computes the physical parameters, ionisation degrees, temperature, density, and the spectrum of the radiated light in each point of the slab, by solving simultaneously the ionisation equations, the equations of statistical equilibrium, the thermal equations and the radiation transfer, using iteration processes.

United States Naval Observatory, Flagstaff Station
Description:
The U.S. Naval Observatory (USNO) announces the release of the first version of the Naval Observatory Merged Astrometric Dataset (NOMAD). The 100 GB dataset contains astrometric and photometric data for over 1 billion stars derived from the Hipparcos, Tycho-2, UCAC2, and USNO-B catalogs for astrometry and optical photometry, supplemented by 2MASS near-infrared photometry. For each unique star the "best" astrometric and photometric data are chosen from the source catalogs and merged into a single dataset. A sequence of priorities is followed and NOMAD contains flags to identify the source catalogs and gives cross-reference identifications. This first release of NOMAD is not a compiled catalog; that is, if a star is identified in more than 1 of the above mentioned catalogs, only 1 catalog entry is chosen. Thus the local and global systematic errors of the various source catalogs will be present in this version of NOMAD. All source catalogs astrometric data are on the International Celestial Reference System within the limitations of the source catalogs. For more information and data retrieval see our homepage www.nofs.navy.mil/nomad.
NSSDC is the permanent archive for NASA space science mission data: astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science. As permanent archive, NSSDC teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and to the general public. NSSDC also serves as NASA's primary active archive for space physics mission data and for selected NASA astrophysics missions. It provides access to several geophysical models and to data from some non-NASA mission data. In addition to supporting active space physics and astrophysics researchers, NSSDC also supports the general public both via several public-interest web-based services (e.g., the Photo Gallery) and via the offline mailing of CD-ROMs, photoprints, and other items. NSSDC provides online information about NASA and non-NASA spacecraft and experiments, and about data management standards and technologies.

observations (Forget et al. 2009, Lebonnois et al. 2006). The database
also includes the full dataset of four Martian years of aerosol
extinction profiles from SPICAM UV solar occultations (Määttänen et
al. 2013).
VO-compliant publication of Schmidt survey SRC-J of the southern sky digitized with the MAMA microdensitometer at the Observatoire de Paris Image Analysis Centre (CAI).
The main activity at Nançay is the development and application of new radio techniques to fundamental research in astrophysics and astronomy. A number of instruments are operated on behalf of researchers in France and worldwide to conduct scientific programmes of observation of the Universe, including the nearby Earth-Space environment, the study of the Sun and the solar system, and the study of distant stars and galaxies in the Universe.

Planetary Data System
Description:
Vector magnetic field data acquired by the Fluxgate Magnetometer
instrument aboard the MAVEN spacecraft. The data are calibrated and
provided in physical units (nT). The time resolution depends on the
telemetry rate available when the data were taken. The data are
expressed in Payload coordinates.

A short course on the VO's SQL-like query language, the Astronomical
Data Query Language. It also covers basic operation of some TAP user
agents. It is available as a multipage HTML rendering for online
perusal as well as a one-file PDF.
Since 1973, the 18-cm lines of the OH radical have been
systematically observed in a number of comets with the Nançay radio
telescope. This allowed an evaluation of the cometary water production
rates and their evolution with time, as well as a study of several
physical processes: the excitation mechanisms of the OH radio lines,
the expansion of the cometary atmospheres, their anisotropy in
relation with non-gravitational forces, the Zeeman effect in relation
with the cometary magnetic field. The Nançay observations of 53
cometary apparitions between 1982 and 2009 are now organized in this
database.
The NASA/IPAC Extragalactic Database (NED) provides a comprehensive fusion
of multi-wavelength data for hundreds of millions of objects located beyond
the Milky Way galaxy. As new observations are published in NASA mission
archives, journal articles and sky survey catalogs, they are cross-identified
with prior measurements and integrated in a unified database. Numerous derived
quantities are also provided to facilitate scientific research. For more
