Some of the tools in this package ask you to specify the format
of input tables using the -f
or -ifmt
flag.
The following list gives the values usually allowed for this
(matching is case-insensitive):
-
fits
- FITS format - FITS binary or ASCII tables can be read.
By default the first table HDU in the file will used, but this can
be altered by supplying the HDU index after a '#' sign,
so "table.fits#3" means the third HDU extension.
-
votable
- VOTable format - any legal, and many illegal 1.0 or 1.1 format
VOTable document can be read.
By default the first
TABLE
element is used,
but this can be altered
by supplying the 0-based index after a '#
' sign,
so "table.xml#4" means the fifth TABLE
element in the document.
-
ascii
- Plain text file with one row per column
in which columns are separated by whitespace.
-
csv
- Comma-Separated Values format,
using approximately the convensions used by MS Excel.
-
wdc
- World Datacentre Format (experimental).
For more details on these formats, see the descriptions in
SUN/252.
In some cases (when using VOTable or FITS format tables) the
tools can detect the table format automatically, and no explicit
specification is necessary. If this isn't the case and you omit
the format specification, the tool will fail with a suitable error
message. It is always safe to specify the format explicitly,
and may lead to more helpful error messages in the case that the
table can't be read correctly.
