"Measurement accuracy" refers to how close a measurement is to the true or correct value. In simpler terms, it means how accurate or precise a measurement is. Full definition
The uncertainties due to sampling and measurement accuracy go into the error bars, and the trend is clearly significant. (realclimate.org)
The early implementation of LLOWFS at LESIA, Observatoire de Paris demonstrated an open loop measurement accuracy of 0.01 lambda / D for tip - tilt at 638 nm when used in conjunction with a four quadrant phase mask (FQPM) in the laboratory. (arxiv.org)
