    keyword=Spot++ raster current scan

    Spot++ raster current scan. Run 4717.  Current 10uA, s0 rate is about 5.5kHz.  
    The hole looks centered.  
    Going to now move to Loop 1 and put 5uA to see boiling and alignment/raster 
    size/fan speed settings.  Since we will not spend a large amount of time doing 
    a careful target-beam alignment tonight, we may want to reduce the raster size 
    a bit to be safer (since we expect the boiling will be less).
