   Calibration and Error Sources
   Accurate measurement requires diligent calibration, especially addressing systematic errors inherent in the sensor housing or orientation. A common error source, particularly for vector instruments deployed in high-altitude aerial surveys, is Orientation Flux Contamination ($\text{OFC}$). This occurs when the sensor's internal alignment drifts due to thermal expansion of the mounting struts, causing a small fraction of the ambient [field](/entries/m…
