IL = 114.8583 -  114.7968 = 0.0614 dB

Error limits (3 sigma) +/- 0.0011 dB

Errors are estimated from too few data points so
error estimation for this particular measurement is 
uncertain.
There are many measurements in this series so the statistics
of all the errors estimates will give a good idea about errors.
