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 + ---- ------------ --------- ------------ --------- --------- --------- --------- + 1 147.000 12.124 0.000 0.000 1600.00 0.092 0.008 + 2 625.000 25.000 0.000 0.000 6976.00 0.090 0.004 + 3 1442.000 37.974 0.000 0.000 15936.00 0.090 0.002 + + + # background-subtracted results + reg net_counts error background berror area surf_bri surf_err + ---- ------------ --------- ------------ --------- --------- --------- --------- + 1 147.000 12.124 0.000 0.000 1600.00 0.092 0.008 + 2 478.000 21.863 0.000 0.000 5376.00 0.089 0.004 + 3 817.000 28.583 0.000 0.000 8960.00 0.091 0.003 + + + # the following source and background components were used: + source_region(s) + ---------------- + ann 512 512 0 9 n=3 + + reg counts pixels sumcnts sumpix + ---- ------------ --------- ------------ --------- + 1 147.000 25 147.000 25 + 2 478.000 84 625.000 109 + 3 817.000 140 1442.000 249 + + +There are four tables in this output.
