+
+
+
+B<funtbl - extract a table from Funtools ASCII output>
+
+
+
+=head1 SYNOPSIS
+
+
+
+
+
+funtable [-c cols] [-h] [-n table] [-p prog] [-s sep] <iname>
+

+=head1 DESCRIPTION
+
+
+
+
+[NB: This program has been deprecated in favor of the ASCII text processing
+support in funtools. You can now perform fundisp on funtools ASCII output
+files (specifying the table using bracket notation) to extract tables
+and columns.]
+
+The B<funtbl> script extracts a specified table (without the
+header and comments) from a funtools ASCII output file and writes the
+result to the standard output.  The first non-switch argument is the
+ASCII input file name (i.e. the saved output from funcnts, fundisp,
+funhist, etc.). If no filename is specified, stdin is read. The
+-n switch specifies which table (starting from 1) to extract. The
+default is to extract the first table.  The -c switch is a
+space-delimited list of column numbers to output, e.g.  -c "1 3 5"
+will extract the first three odd-numbered columns. The default is to
+extract all columns. The -s switch specifies the separator string to
+put between columns. The default is a single space. The -h switch
+specifies that column names should be added in a header line before
+the data is output. Without the switch, no header is prepended.  The
+-p program switch allows you to specify an awk-like program to run
+instead of the default (which is host-specific and is determined at
+build time). The -T switch will output the data in rdb format (i.e.,
+with a 2-row header of column names and dashes, and with data columns
+separated by tabs). The -help switch will print out a message
+describing program usage.
+
+
+For example, consider the output from the following funcnts command:
+
+  [sh] funcnts -sr snr.ev "ann 512 512 0 9 n=3"
+  # source
+  #   data file:        /proj/rd/data/snr.ev
+  #   arcsec/pixel:     8
+  # background
+  #   constant value:   0.000000
+  # column units
+  #   area:             arcsec**2
+  #   surf_bri:         cnts/arcsec**2
+  #   surf_err:         cnts/arcsec**2
+  
+  # summed background-subtracted results
+  upto   net_counts     error   background    berror      area  surf_bri  surf_err

+
+There are four tables in this output. To extract the last one, you
+can execute:
+
+  [sh] funcnts -s snr.ev "ann 512 512 0 9 n=3" | funtbl -n 4
+  1 147.000 25 147.000 25
+  2 478.000 84 625.000 109
+  3 817.000 140 1442.000 249
+
+Note that the output has been re-formatted so that only a single space
+separates each column, with no extraneous header or comment information.
+
+
+To extract only columns 1,2, and 4 from the last example (but with a header
+prepended and tabs between columns), you can execute:
+
+  [sh] funcnts -s snr.ev "ann 512 512 0 9 n=3" | funtbl -c "1 2 4" -h -n 4 -s "\t"
+  #reg    counts  sumcnts
+  1       147.000 147.000
+  2       478.000 625.000
+  3       817.000 1442.000
+
+
+Of course, if the output has previously been saved in a file named
+foo.out, the same result can be obtained by executing:
+
+  [sh] funtbl -c "1 2 4" -h -n 4 -s "\t" foo.out
+  #reg    counts  sumcnts
+  1       147.000 147.000
+  2       478.000 625.000
+  3       817.000 1442.000
