- joburl=<url-value>
The URL of a job created by submission of a TAP query
which was created earlier and has not yet been deleted (by the client) or
destroyed (by the server). This will usually be of the form
<tap-url>/async/<job-id>. You can also find out, and
possibly retrieve results from the job by pointing a web browser at this URL.
- compress=true|false
If true, the service is requested to provide HTTP-level
compression for the response stream (Accept-Encoding header is set to
"
gzip", see RFC 2616). This does not guarantee that
compression will happen but if the service honours this request it may result
in a smaller amount of network traffic at the expense of more processing on
the server and client.
- poll=<millisec>
Interval to wait between polling attempts, in
milliseconds. Asynchronous TAP queries can only find out when they are
complete by repeatedly polling the server to find out the job's status. This
parameter allows you to set how often that happens. Attempts to set it too low
(<50) will be rejected on the assumption that you're thinking in seconds.
- progress=true|false
If this parameter is set true, progress of the job is
reported to standard output as it happens.
- delete=finished|never|always|now
Determines under what circumstances the UWS job is to be
deleted from the server when its data is no longer required. If it is not
deleted, then the job is left on the TAP server and it can be accessed via the
normal UWS REST endpoints or using
tapresume until it is destroyed by
the server.
Possible values:
- finished: delete only if the job finished, successfully or not
- never: do not delete
- always: delete on command exit
- now: delete and return immediately
- ocmd=<cmds>
Specifies processing to be performed on the output table,
after all other processing has taken place. The value of this parameter is one
or more of the filter commands described in SUN/256. 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 a value of
"@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, and lines which are blank
or which start with a '#' character are ignored.
- omode=out|meta|stats|count|checksum|cgi|discard|topcat|samp|tosql|gui
The mode in which the result table will be output. The
default mode is
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
- checksum
- cgi
- discard
- topcat
- samp
- tosql
- gui
Use the
help=omode flag or see SUN/256 for more information.
- out=<out-table>
The location of the output table. This is usually a
filename to write to. If it is equal to the special value "-" (the
default) the output table will be written to standard output.
This parameter must only be given if omode has its default
value of "out".
- ofmt=<out-format>
Specifies the format in which the output table will be
written (one of the ones in SUN/256 - matching is case-insensitive and you can
use just the first few letters). If it has the special value
"
(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".
