[News] new version of standard star catalog

[Gijs Verdoes Kleijn]

Dear Astro-WISE users,

A new version of the standard star catalog (version 10) has been released.
One thing has changed with respect to version 9:
Improved coordinates are used for the 526 Landolt stars available at 
this ESO webpage: http://www.ls.eso.org/lasilla/Telescopes/2p2T/Landolt/
The attached AngularSep.eps figure shows a histogram of the angular 
separation between previous and improved coordinates. Most changes are 
within ~5arcsec but some stars had coordinates off by tens of arcsecs in 
the original catalog (Landolt 1992 AJ 104, 340).

The how-to reflects this new version:

The standard star catalog version 10 is now the default catalog used in 
photometric calibrations in Astro-WISE. I am very much interested in all 
feedback regarding the use of this new standard star catalog. Please 
feel free to contact me if you have any questions related to the 
standard star catalog.

Kind regards, Gijs
