MICHBACK V1.0 ASCII DEFLECTION DATA

The data before the separator line below is optional.  The separator
line, consisting of 80 "=" signs, must appear in each file followed by
the required data formatted according to the instructions given below.


Instructions
------------
1) Make a backup copy of this file for a permanent record.

2) Arrange your deflection data in the column format shown at the bottom
   of this file.  The data following the separator line are as follows:
   a) An E or S to identify English or SI units for all data in this
      file must be typed in the first column of the first line.  If the
      system of units specified in this file is different from that
      specified in MICHBACK, then the deflection data in this file will
      be converted to correspond to the units being used in MICHBACK. 
   b) The number of drops per test must be typed at the beginning of the
      second line.
   c) The target load must be typed at the beginning of the third line.  
      All deflections are scaled linearly to correspond to the target 
      load prior to backcalculation.
   d) The fourth, fifth and sixth lines are ignored.
   e) The deflection data begins at the eight line, and n+3 columns are
      required, where n=number of sensors.
   f) Columns may be separated by spaces or tabs.
   g) The number of drops at each station must be the same.
   h) Deflections for each test are grouped together.  The station
      location and pavement temperature must be entered on the first line of
      the group along with the deflections measured for the first drop.
      Deflections for subsequent drops must be entered on consecutive
      lines.  Deflections for different test locations must be separated
      by a blank line.

3) Cross-section data, number of sensors, and other pertinent information
   must be input directly in MICHBACK.
