Status of 511 keV line Imaging Imaging in the 500-520 keV band is yielding weak detections with 9R and 9F. No detections with other RMCs 9F imaged flux is consistently higher than 9R At least 50% of imaged 500-520 keV flux is from continuum Continuum imaged flux is consistently higher in 9F than 9R Off-diagonal response is important. No useful positron annihilation line imaging yet.
