NAME¶
Table - read and write ASCII and FITS tables
SYNOPSIS¶
asttable [OPTION...] ASTRdata
DESCRIPTION¶
Table is part of GNU Astronomy Utilities 0.19. 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:
- $ asttable -P
- Inputs/Outputs and options:
- $ info asttable
- Full section in manual/book:
- $ info Table
- Full Gnuastro manual/book:
- $ info gnuastro
If you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and developers. For more information, please run:
