docsPnmCmtsUsHistSymmetry

This attribute is used to indicate whether 256 or 255 bins were used
for the measurement.
              
Even Symmetry = 'false' (default):
The histogram has even symmetry about the origin. There is no bin center
lying directly at the origin; rather, two bin centers straddle the origin
at 0.5. All bins with indices 0-255 contain valid hit-count data.
The histogram bin centers are offset from the corresponding 8-bit
twos-complement integer values by 1/2, that is, bin center = twos complement
value + 0.5.
              
Odd Symmetry = 'true':
The histogram has odd symmetry about the origin. There is a bin center
lying at the origin. The bin with index 0 is not used and returns the
value 0. The bins with indices 1 to 255 contain valid hit-count data.
The histogram bin centers are located on the corresponding 8-bit
twos-complement integer values.
              
The following table shows the defined histogram bin centers for the
cases of even and odd symmetry.

This object cannot be changed while a capture is in progress. The CMTS
return a value of 'inconsistentValue' if set while the value of
'docsPnmCmtsUsHistMeasStatus' is 'busy'.
