NAME

       Table - read and write ASCII and FITS tables

SYNOPSIS

       asttable [OPTION...] ASTRdata

DESCRIPTION

       Table  is  part  of  GNU  Astronomy  Utilities  0.16.   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

       and developers. For more information, please run:
