The usage of multicone
is
stilts <stilts-flags> multicone ifmt=<in-format> istream=true|false icmd=<cmds> ocmd=<cmds> omode=<out-mode> <mode-args> out=<out-table> ofmt=<out-format> serviceurl=<value> ra=<expr> dec=<expr> sr=<expr> verb=1|2|3 copycols=<colid-list> zerometa=true|false force=true|false [in=]<table>If you don't have the
stilts
script installed,
write "java -jar stilts.jar
" instead of
"stilts
" - see Section 3.
The available <stilts-flags>
are listed
in Section 2.1.
Parameter values are assigned on the command line as explained in Section 2.3. They are as follows:
copycols = <colid-list>
dec = <expr>
force = true|false
zerometa
).
Some (broken) services refuse to honour this initial request,
making it look like they don't work when in fact they do.
If this parameter is set true
then even if the
initial query fails, the task will continue to attempt the
data queries.
[Default: false
]
icmd = <cmds>
The value of this parameter is one or more of the filter commands described in Section 5.1. If more than one is given, they must be separated by semicolon characters (";"). This parameter can be repeated multiple times on the same command line to build up a list of processing steps. The sequence of commands given in this way defines the processing pipeline which is performed on the table.
Commands may alteratively be supplied in an external file,
by using the indirection character '@'.
Thus "icmd=@filename
"
causes the file filename
to be read for a list
of filter commands to execute. The commands in the file
may be separated by newline characters and/or semicolons.
ifmt = <in-format>
(auto)
(the default),
then an attempt will be
made to detect the format of the table automatically.
This cannot always be done correctly however, in which case
the program will exit with an error explaining which
formats were attempted.
[Default: (auto)
]
in = <table>
ifmt
parameter.
istream = true|false
in
table
will be read as a stream.
It is necessary to give the
ifmt
parameter
in this case.
Depending on the required operations and processing mode,
this may cause the read to fail (sometimes it is necessary
to read the input table more than once).
It is not normally necessary to set this flag;
in most cases the data will be streamed automatically
if that is the best thing to do.
However it can sometimes result in less resource usage when
processing large files in certain formats (such as VOTable).
[Default: false

ocmd = <cmds>
The value of this parameter is one or more of the filter commands described in Section 5.1. If more than one is given, they must be separated by semicolon characters (";"). This parameter can be repeated multiple times on the same command line to build up a list of processing steps. The sequence of commands given in this way defines the processing pipeline which is performed on the table.
Commands may alteratively be supplied in an external file,
by using the indirection character '@'.
Thus "ocmd=@filename
"
causes the file filename
to be read for a list
of filter commands to execute. The commands in the file
may be separated by newline characters and/or semicolons.
ofmt = <out-format>
(auto)
"
(the default),
then the output filename will be
examined to try to guess what sort of file is required
usually by looking at the extension.
If it's not obvious from the filename what output format is
intended, an error will result.
This parameter must only be given if
omode
has its default value of "out
".
[Default: (auto)
]
omode = <out-mode> <mode-args>
out
, which means that
the result will be written as a new table to disk or elsewhere,
as determined by the out
and ofmt
parameters.
However, there are other possibilities, which correspond
to uses to which a table can be put other than outputting it,
such as displaying metadata, calculating statistics,
or populating a table in an SQL database.
For some values of this parameter, additional parameters
(<mode-args>
)
are required to determine the exact behaviour.
Possible values are
out
meta
stats
count
cgi
discard
topcat
plastic
tosql
help=omode
flag
or see Section 5.4 for more information.
[Default: out
]
out = <out-table>
This parameter must only be given if
omode
has its default value of "out
".
[Default: -

ra = <expr>
serviceurl = <value>
name=value
", separated by '&' characters).
If this value does not end in either a '?' or a '&',
one will be added as appropriate.
Note that the regquery
command can be used to locate the service URL for cone search
services.
sr = <expr>
verb = 1|2|3
zerometa = true|false
multicone
.
The default setting of false instead picks up the metadata
from the first non-empty data request. This is less likely
to fail, but doesn't stream data so well on output.
[Default: false
