Resource Description:
For a list of all services and tables belonging to this table's resource, see Information on resource 'ppmxl/q'
This table has an associated publication. If you use data from it, it may be appropriate to reference 2010AJ....139.2440R (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.
To cite the table as such, we suggest the following BibTeX entry:
@MISC{vo:ppmxl_main, year=2009, title={Untitled Resource}, author={Röser, S.; Demleitner, M.; Schilbach, E.}, url={http://data.xao.ac.cn/tableinfo/ppmxl.main}, howpublished={{VO} resource provided by the {XAO} Data Center} }
To query this data, you can use
You can retrieve also the whole data set as a gzipped text file from http://vo.ari.uni-heidelberg.de/ppmxl (39.4 GiB). The columns in the text file are in database order as documented in the table info in DB order with columns separated by vertical bars ("|").
David Tholen kindly provided code to convert this into a collection of files for easy consumption by FORTRAN programs.
Sorted by DB column index. [Sort alphabetically]
