Description:
miror service of Observed spectra and their fitted models for galaxies
from RCSED catalog (derived from cross-match between SDSS, GALEX, and
UKIDSS catalogs)
The stellar spectra service is a compilation of several libraries
distributed by large observatories, which are intended to calibrate
telescopic observations. It currently provides access to two libraries
of reference stars distributed by ESO (composite spectra:
https://www.eso.org/sci/observing/tools/standards/IR_spectral_library.html)
and NASA IRTF (observations from SpeX:
http://irtfweb.ifa.hawaii.edu/~spex/IRTF_Spectral_Library/References_files/All.html).
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.
