Optical and UV Spectrophotometric Standard Stars |
This resource consists of a set of WWW pages each devoted to a
single spectrophotometric standard star and containing positional
information, magnitude, a finding chart and plots of the magnitude
and flux against wavelength. The Right Ascension
and Declination
are in the HST Guide Star Catalogue coordinates (equinox 2000).
The finding charts have the conventional orientation, north at the
top and east to the left and the image dimensions are indicated. If
not arrowed, the standard star is the one in the centre of the field.
Access to the standards is either through:
an RA ordered list;
an RA-Dec sky map with star positions to enable the closest
standard star to your observed source to be quickly identified.
The data for the standard stars come from four sources:
The data from which the plots were produced are also available at ftp://ftp.eso.org/pub/stecf/standards from the standard star pages.
Some of the finding charts were produced from the Digitized Sky Survey produced by STScI and based on plate material from the UK Schmidt Telescope and the Oschin Schmidt Telescope.
