Average calculation based on number of rows

Dear users,

I need your support, I have a file like this:

Code:

272134.548 6680572.715
272134.545 6680572.711
272134.546 6680572.713
272134.548 6680572.706
272134.545 6680572.721
272134.543 6680572.710
272134.544 6680572.715
272134.543 6680572.705
272134.540 6680572.720
272134.544 6680572.721
 
272134.539 6680572.714
272134.260 6680573.092

272101.962 6680565.280
272101.903 6680565.156
272101.912 6680565.159
272101.912 6680565.156
272101.905 6680565.158
272101.899 6680565.169
272101.899 6680565.161
272101.894 6680565.173
272101.894 6680565.169

And I need to get the first values block before the row without data (then the second values block before the blanck line and so on), and calculate the simple average value for each row, this is, sum all numbers and divide it by the number of values. I did the following bucle to separate the first values until it finds the blank line but doesn't work:

Code:

while read file
do
        file=($list.txt)
        awk '{ print $1, $2 }' file | awk NF | echo ""${line[0]}" "${line[1]""
done

Separately, I used wc -l to count the values but the file name appears (let's say: wc -l list.txt gives 10 list.txt).

I would appreciate your support to solve my problem.

Thanks in advance.

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
