---|---|---|---|---|
C | antpos.090414 | Apr. 14, 2009 -- ... | C-config solution | refant=C8. Vernesa used an iterative process: "First the slope-500MHz method reaches a ~6cm accuracy. Then taking the upper/lower sidebands separately yields a ~0.5 cm accuracy. Finally applying these solutions to the initial data set resulted in the attached positions." Here are phase vs. time plots before and after the solutions have been applied. "The formal uncertainties on the (x,y,z) positions are better than 0.1mm. However, the phase scatter of the fit is larger than in optimal conditions [mean~0.4 radian (usually 0.2-0.3), reaching up to >0.6rad for C1, C2, C4], so another track would be useful." |
