Table - read and write ASCII and FITS tables
asttable [OPTION...] ASTRdata
Table is part of GNU Astronomy Utilities 0.14. Table can be used
to view the information, select columns, or convert tables. The inputs and
outputs can be plain text (with white-space or comma as delimiters), FITS
ascii, or FITS binary tables. The output columns can either be selected by
number (counting from 1), name or using regular expressions. For regular
expressions, enclose the value to the '--column' ('-c') option in slashes
('\', as in '-c\^mag\'). To print the selected columns on the command-line,
don't specify an output file.
For more information, please run any of the following commands. In
particular the second contains a very comprehensive explanation of Table's
invocation: expected input(s), output(s), and a full description of all the
options.
- All options and their
values:
