The ephemeris were produced by simulating the ejection of meteoroids
from the sunlit hemisphere of cometary nuclei, typically from 0 to 3
au, followed by the propagation of orbits of meteoroids in the Solar
System, taking into account the gravity of the Sun, the 8 planets,
Pluto, and the Moon, as well as the radiation pressure and the
Poynting-Robertson drag. Note that asteroid parent bodies were
considered as active (i.e. comet-like bodies) even if they are not
active today. The showers are predicted when a planet enters a large
enough set of meteoroids, at a distance less than typically 0.01 au.

VOPSAT is a set of southern sky digital surveys based on ESO-R, SRC-J and POSS1-E atlases. The plates have been digitized with the MAMA microdensitometer with a resolution of 0.7 arc-sec. Pixel resampling will allow mosaicing neighbouring Schmidt fields up to hundreds of square degrees.
The Miriade project aims to provide a VO-compliant suite of services to compute positional and physical ephemerides of known solar system bodies as seen from any location on Earth as well as various location in space (HST, SPITZER, Gaia, etc.)
VOTT is a formatted list of educational/outreach texts on using the
VO: use cases, tutorials, courses, and such. VOTT contains material
for all settings, from pre-school to graduate. It is generated from
the documents known to the VO Registry.
Voyager 1 Magnetometer Jupiter Resampled Heliographic (RTN) Coords
48.0 Second Data Collection
Short Name:
VG1_MAG_J_48S
Date:

Publisher:
Planetary Data System
Description:
This collection contains calibrated magnetic field data acquired by
the Voyager 1 Low Field Magnetometer (LFM) during the Jupiter
encounter. Coverage begins in the solar wind inbound to Jupiter and
continues past the last outbound bowshock crossing. The data are in
Heliographic (RTN) coordinates and have been averaged from the 9.6
second summary data to a 48 second sample rate. All magnetic field
measurements are given in nanoTesla (nT).
Voyager 2 Magnetometer Jupiter Resampled Heliographic (RTN) Coords
1.92 Second Data Collection
Short Name:
VG2_MAG_HG1.92S
Date:

Publisher:
Planetary Data System
Description:
This collection contains Voyager 2 Jupiter encounter magnetometer
data given in Heliographic coordinates and averaged from the 60 ms
instrument sample rate to a 1.92 second resampled rate. All magnetic
field observations are measured in nanoTesla. All of the magnetic
field data are calibrated.
