is not yet implemented in ESPACE. There is a correlation between
focal plane position and target vertical position which is not corrected,
hence we get a spread in Em. Final point: raster concentrates at
the edges, so we get a double-peak structure with a smear in between.
Nilanga made the plot below which shows the Em vs the beam vertical
position. Figure two below is nilanga's by-hand correction which
shows no double-peak structure.
We estimate about 300k counts in the 2bbu region with following
cuts: 960
no other cuts that i am aware of, but I am using xiaodong's espace file
which contains lots of stuff i don't want to take the time to understand
