Description:
These observations cover five star-forming regions in the Andromeda
galaxy (M31) with optical integral field spectroscopy. Each has a
field of view of roughly 1 kpc across, at 10pc physical resolution. In
addition to the calibrated data cubes, we provide flux maps of the Hβ,
[OIII]5007, Hα, [NII]6583, [SII]6716 and [SII]6730 line emission. Line
fluxes have not been corrected for dust extinction. All data products
have associated error maps.
PPM-Extended (PPMX) is a catalogue of 18 088 919 stars on the ICRS
system containing astrometric and photometric information. Its
limiting magnitude is about 15.2 in the GSC photometric system.
Within this case you learn that stars that seem "fixed" on the sky
may actually move, even if their motion is so slow for the naked eye
to be undetectable. You compare two photographs of the Barnard's Star
taken several years apart and will be able to estimate its
displacement on the sky. Your estimate will be very close to actual
measurements.
This authority is used by the purx publishing registry proxy and
hence contains records from (potentially) a multitude of publishers
that just put their registry records on a common web server. Problems
with actual records served here should be reported to the resources'
contact addresses first. Non-responsive contacts should be reported to
the contact persons of this authority.
This is the OAI-PMH endpoint of the purx publishing registry proxy.
purx lets you publish VOResource records by just putting XML into a
web browser. For details, see http://dc.g-vo.org/PURX.
This catalogue (with updates to the pervious version) contains 11358
(+2759) quasars (defined as brighter than absolute B magnitude -23),
3334 (+501) AGNs (defined as fainter than absolute B magnitude -23)
and 357 (+137) BL Lac objects from 1863 (+201) references.
The RAdial Velocity Experiment (RAVE) contains stellar atmospheric
parameters (effective temperature, surface gravity, overall
metallicity), radial velocities, chemical abundances and distances.
Observations between 2003 and 2013 were used to build the five RAVE
data releases.
