Beam-target double-spin asymmetries and target single-spin asymmetries were
measured for the exclusive $\pi^0$ electroproduction reaction $\gamma^* p \to p
\pi^0$, expanding an analysis of the $\gamma^* p \to n \pi^+$ reaction from the
same experiment. The results were obtained from scattering of 6 GeV
longitudinally polarized electrons off longitudinally polarized protons using
the CEBAF Large Acceptance Spectrometer at Jefferson Lab. The kinematic range
covered is $1.1
