keyword=re: raster current measurements
According to halog 194887 and the work Brandon did, it appears the
raster current in our DAQ is non-uniform. It's hard to believe that
this is physical but it's still a potential problem because analysis
folks like to use the raster current to correct for beam position
(it has the advantages of having a fast frequency response and little
time lag to the data). It looks as if some bit was bad in the Fastbus
ADC. I'll investigate it ...
