Following are the results of the post-project sonic wind offsets measured in the EOL calibration laboratory Calibration Laboratory temperature chamber.
"ok" indicates u.x and v u.y offsets < +/-4 cm/sec and u.z (w) offsets < +/-2 cm/sec.
Non Non-ok entries are the temperature range within which specs were exceeded and the maximum offset.
Click on the "EOL pre/post-Offset PLotsPlots" calibration date dates to see the offset plots as a function of temperature. For sonics "on top" use the red data curves (chamber temperature increasing with time) and for sonics "on bottom" use the black curves (chamber temperature decreasing), i.e. the curve with the smaller variance.
