  Sunward-flowing voids above post-coronal mass ejection flare arcades, also
known as supra-arcade downflows (SADs), have characteristics consistent with
post-reconnection magnetic flux tube cross-sections. Applying semi-automatic
detection and analysis software to a large sample of flares using several
instruments (e.g., Hinode/XRT, Yohkoh/SXT, TRACE, and SOHO/LASCO), we have
estimated parameters such as speeds, sizes, heights, magnetic flux, and
relaxation energy associated with SADs, which we interpret as reconnection
outflows. We also present speed and height measurements of shrinking loops in
comparison to the SAD observations. We briefly discuss these measurements and
what impact they have on reconnection models.
