NAME
adumpcat -- query a catalog and capture the results
.ih
USAGE
adumpcat catalog output ra dec size
.ih
PARAMETERS
.ls catalog
The name of the catalog to be queried. Catalog names have the form
catalog@site, e.g. "usno2@noao". The catalog address and query format are
stored in a record called catalog in the catalog configuration file.
.le
.ls output
The name of the output query results file. The query results are written
to the output file without modification, i.e. they may contain comments,
HTML markup, etc as well as the object list.
.le
.ls ra
The right ascension of the field center in the units expected by the catalog
query. The value of ra replaces the default value of the ra query parameter.
.le
.ls dec
The declination of the field center in the units expected by the catalog query.
The value of dec replaces the default value of the dec query parameters.
It may be necessary to add or remove a leading + to make the query work
correctly.
.le
.ls size
The field size in units expected by the catalog query. The value of size
replaces the default value of the width, ra/xwidth, dec/ywidth,
hwidth, x/rahwidth, y/dechwidth, or radius query parameters as appropriate.
.le
.ls catdb = ")_.catdb"
The catalog configuration file. The name of the catalog configuration file
defaults to the value of the package parameter of the same name. The
default configuration file is "astcat$lib/catdb.dat".
.le
.ih
DESCRIPTION
Adumpcat is a simple catalog access debugging task which queries the
astrometric catalog \fIcatalog\fR, captures the results, and writes them
to the file \fIoutput\fR without modification.
The user must supply values for the query parameters ra, dec, and one or
more of the size query parameters width, ra/xwidth, dec/ywidth, hwidth,
ra/xhwidth, dec/yhwidth, or radius by
specifying appropriate values for the \fIra\fR, \fIdec\fR, and \fIsize\fR
parameters in the units expected by the catalog query. These values are
treated as strings and passed directly to the catalog query without
coordinate transformations or units conversions.
The catalog configuration file \fIcatdb\fR contains a record for each
supported \fIcatalog\fR. This record contains the catalog address,
the query format, and the output format. The default configuration file
is "astcat$lib/catdb.dat".
The output of adumpcat can be used to refine the catalog record in the
catalog configuration file.
.ih
EXAMPLES
1. List the supported catalogs, select a catalog to query, make the query,
and capture the results. The aclist task is used to list the supported
catalogs, as well as to list the query and output formats for the selected
catalog as shown below. The query format tells the user that the input
ra and dec must be entered in J2000 sexagesimal hours and degrees and
that the size parameter is a halfwidth in minutes. In this case the
results containing leading and trailing comments and
HTML markup as shown below.
