Hi Hugh,

Interesting. This cross section through the coma appears to show a different story to this vertical section.

Perhaps there could be some directional effects in the differences between Dust,Na D and other emission bands with the gas emission moving off the slit to the left relative to the dust.  I have some cross sections across the tail still to analyse  which might shed more light.

Cheers

Robin
