The cdsclient package is a set of C and shell routines which can be built on Unix stations or PCs running Linux, which once compiled allow to query some databases located at CDS or on mirrors over the network.
The cdsclient package includes two generic query programs:
Specific programs like find2mass or finducac3 are connecting directly to one of the very large surveys available from CDS (a very large survey has 107 or more rows). Using a specific program is faster than the generic vizquery program which has to locate and transport the data via data-base queries; but such progams exist only for the list of enumerated large surveys below.
The tar file is available at http://cdsarc.u-strasbg.fr/ftp/pub/sw/cdsclient.tar.gz or as the file cdsclient.tar.gz in the ftp://cdsarc.u-strasbg.fr/pub/sw/ directory.
tar xvfz cdsclient.tar.gz
(the z option is available in the GNU tar; if your installation
doesn't know the z option, execute
gzip -cd cdsclient.tar.gz | tar xvf -
A subdirectory cdsclient-V.vv
(where V.vv represents the
version number) is created; move to that directory
(on some old versions of System V, you might need to type sh configure )
If you wish a final installation (executables, libraries, and manpages)
in a non-standard directory tree structure (the default is
/usr/local), specify the preferred prefix, e.g.
to prepare an installation of executables in your ~/bin directory — an installation which does not require any root privilege.
There are several query programs; as a rule, each program can be executed with the -help option to list the basic available options, e.g.
A -HELP option is also available for details on the column contents for the programs that return data, like findgsc or findpmm
findcat [key... | catalogue_number]
keys are words to look for, e.g. RADIO, Author's name, etc..., or catalogue number e.g. 8059 B/hst J/A+AS/94/519
lscat catalogue_number [catalogue_number...]
catcat [-#] [-fits[.Z|.gz]|-tar[.Z|.gz] catalog[/file]
-#: Specify how many lines from each file (default
all) are to be printed.
-tar: Get catalogue file(s) in TAR format
compressed versions as tar.Z (Unix compress) or tar.gz (gzip)
-fits: Get catalogue file(s) as FITS tables
compressed versions as fits.Z (Unix compress) or fits.gz (gzip)
catalog: catalog designation, e.g. 8059, VIII/59, J/A+AS/94/519 ...
