Total field sensor comparison

During the XIIIth IAGA Workshop (hereafter referred to as “the workshop"), several total field comparison measurements were conducted at the Boulder Magnetic Observatory (BOU). The purpose of these tests was to look for errors within the total field instruments which are considered “absolutes” instruments. The total field measurement is a critical component of the absolute measurement computation. Samples between two total field sensors, corresponding in time, were directly compared. Other methods for calibration exist for these sensors, including the use of frequency generators (Jankowski and Sucksdorff, 1996). This test was not utilized at this workshop.
