Note: The delay of the X-rays is determined from the cross-correlation between decimetric pulsations and spikes with HXR flux (Tables~\ref{table:1} and~\ref{table:2}). Linear regression is applied and the bisector reported. The function has the form $f=a+b\tau$, where $f$ is the X-ray flux (RHESSI for hard X-ray and GOES for soft X-ray) and $\tau$ is the delay using the Gauss or maximum method.
