stiltsscript installed, write "

Parameter values are assigned on the command line as explained in Section 2.3. They are as follows:
dec = <expr>(String)
icmd = <cmds>(ProcessingStep)
in, before any other processing has taken place. The value of this parameter is one or more of the filter commands described in Section 6.1. 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 a value of "
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.
ifmt = <in-format>(String)
in. The known formats are listed in Section 5.1.1. This flag can be used if you know what format your table is in. If it has the special value
(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. This parameter is ignored for scheme-specified tables.
in = <table>(StarTable)
-", meaning standard input. In this case the input format must be given explicitly using the
ifmtparameter. Note that not all formats can be streamed in this way.
<" character at the start, or a "
|" character at the end ("
<syscmd" or "
syscmd|"). This executes the given pipeline and reads from its standard output. This will probably only work on unix-like systems.
istream = true|false(Boolean)
inparameter will be read as a stream. It is necessary to give the
ifmtparameter 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 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). This parameter is ignored for scheme-specified tables.

0", which treats each position as a point rather than a cone, but a constant or an expression as described in Section 10 may be used instead.
