Notes: Columns are image frequency f; burst onset time t; helioprojective-Cartesian coordinates X and Y ; radial distance of the source according to observation robs , refraction rref , fundamental rf and harmonic rh emission from ray-tracing simulations; electron number density Ne at distance rf ; and Newkirk model parameter α(rf) corresponding to Ne. The statistical error in position is about 0.01 R⊙ .
